When we see Miasma being talked about today, we often only hear of the term Miasma being used, but historically there were multiple terms used when speaking of ritual impurity.
𝐿𝓎𝓂𝒶
♡ Lyma is the everyday spiritual impurities that we incur, it is the basis of what separates us from the Gods, we become afflicted with lyma through any contact with bodily fluids or blood and disease. It can be purified through performing khernips or simply washing yourself before prayer.
♡ When we talk about performing purification before praying or worshipping the Theoi, we are mostly talking about purification from Lyma, although we may still describe substances that emit Lyma as "Miasmic"
♡ Although bodily fluids and blood are considered Miasmic substances, acts that may produce these things are not inherently considered miasmic, as we see the Gods being offered animal sacrifices.
𝑀𝒾𝒶𝓈𝓂𝒶
♡ The term Miasma is frequently used as a catch-all term for any sort of spiritual impurity within' the hellenic framework, however historically Miasma referred to spiritual impurity of more seriousness than Lyma.
♡ Miasma is incurred by contact with death, or blood spilled from violence(i. e, hurting another person), and in order to purify from it you usually need to perform fasting, and/or give offerings to purification deities such as Zeus, Apollon or Hygeia.
♡ If Miasma goes un-purified, it can affect your ability to reconcile with the Gods, and it is considered highly disrespectful to perform formal worship while in a Miasmic state.
𝒜𝑔𝑜𝓈
♡ Agos is considered the most severe form of spiritual impurity, it is incurred through comitting heinous acts of disrespect to the Gods, such as disrespecting a Gods temple, or other extreme acts of sacrilege, it can also be incurred via committing murder.
♡ Agos is often seen as a type of curse, one afflicted with Agos is bound to the deity whom they have offended. It is often believed this curse goes beyond the human realm.
♡ Agos cannot be purified by any mortal means, it can only be purified by divine intercession, often after years and years of penance.
“It’s worth noting that of the 923 occurrences of the word “miasma” in Greek literature, over 600 are found in Christian texts.”
here is an AMAZING post diving into the difference between historical and modern understandings of miasma and purity. i, myself, can be quick to scroll past ‘tap here to read more’, but this is quick read, extremely non-judgmental, and easily digestible! i included a fascinating quote above, and another quote below:
“Our religion is growing and thriving, and as it develops, new understandings naturally arise - which is great! But it’s just as important that, as a community, we strive towards giving an honest representation of what is new and what is historical, so that each individual may make an informed choice of what suits their practise best.”
Lyma (λῦμα) often refers to daily physical and spiritual dirt. Many modern practitioners view this as a milder form of Miasma that happens with daily life. The concept of Miasma is vague to begin with, so oftenly the two are interchanged. Lyma is more commonly seen discussed in online spheres of Hellenic worship.
lyma can be gained by:
childbirth
sex
interaction with the dead
funerals
Most commonly, lyma can be removed by handwashing or bathing.
In Helpol, we have three concepts known as lyma, miasma, and agos.
To some, humans are seen as naturally pure beings, but because we are living mortal creatures, spiritual dirt can cling to us and make us impure.
Here, I will discuss these three types of pollution
(Disclaimer: Some of this information comes from my own personal interpretations, and therefore may not apply to the beliefs of everyone)
Lyma
Lyma means "something to be washed away". Itis generally just physical dirt. It isn't much of a big deal when it comes to spiritual matters. However, it is still best to be free of it when approaching the gods.
Miasma
This is where things get complicated.
Miasma is essentially general spiritual pollution. Miasma is something that is completely unavoidable and should not be shamed (well, depending on the cause). Miasma is mainly caused by things related to life and death. This includes sex, childbirth, visiting a cemetery, blood, sexual fluids, etc.
However, miasma has different degrees of severity. More severe miasma comes from acts such as rape, hubris, murder, etc.
Miasma also spreads from people to people. If you walk past someone on the street who just came back from a funeral, their miasma will cling to you as well. This also highlights how unavoidable miasma is. But usually, this kind of indirect miasma is not as bad.
We are not allowed to approach the gods in a state of miasma. Luckily, miasma is not difficult to get rid off (excluding the more severe cases listed above).
All you need to do is wash your hands.
If you get a cut on your leg, the blood is miasmic and therefore you can't approach the gods. But all you need to do is wait for the bleeding to stop, wash away the blood, wash your hands, and then you're good to go.
There is a debate I once had on whether miasma prevents us from praying, giving offerings, and participating in festivals. To me, the answer is yes, but not with prayers. Let me explain why.
In a very simplified description of a certain myth, Orestes killed his mother. This caused him to enter a state of severe miasma and a state of agos (which I will explain later). Long story short, he prayed and asked Apollon to help purify him, in return for a grand offering later on. Apollon heard the prayer and came to help purify Orestes.
In this example, we see that Orestes was still able to pray to Apollon in the worst state of miasma, but promised to give offerings later on.
This implies that prayer is not an issue with miasma.
Here is another example: You don't need to wash your hands when talking to someone, but you should wash your hands if you want to give that person food.
In a similar way, in my opinion, you don't need to wash your hands for a casual prayer, but you should wash them before giving an offering. Although, I also prefer not to pray when I know I am in a miasmic state.
However, this is my own interpretation and others may have different views.
There are other ways to cleanse miasma such as khernips, incense, and scapegoats.
Ocean water is also said to cleanse miasma extremely well.
Agos
Agos is a cursed state and is the most extreme form of spiritual pollution. However, agos is not easy to get.
If you commit a horrible act such as murder, you will be in a state of extreme miasma. However, when the gods notice your crime and get enraged (keep in mind that it is usually not that easy to anger the gods), the miasma evolves into agos.
Miasma is a naturally occurring thing, but agos only comes from the wrath of the gods.
Agos is difficult to remove and is a pretty big deal.
Luckily, you don't need to worry about agos unless you're a horrible person who commits heinous acts.
Aaaand that is my interpretation of spiritual pollution in Helpol. I hope this post can be helpful to you!
(For the record we don't talk about my username its old) anyways uhm so Ive seen several people say things about it, but not many extensions on it, so can you give sources on or explain Lyma/Maisma??
Zesty sounds like "Warmth" (ζέστη) in Greek xD
Anyways!! Both words are still used in Greek, in both every day and religious contexts, so they're also very easy to understand as a modern Greek. Of course, I will focus on our ancient practices.
Μίασμα / Miasma
In ancient Greek religion (and in Greek Christianity), "miasma" (μίασμα) refers to a form of spiritual or moral pollution or defilement that is contagious and dangerous. The words means “pollution” or “stain.”
It arises from certain actions considered offensive to the gods - such as murder - or physically contagious/dangerous events such as childbirth, or contact with dead bodies. Basically they took the "man, you need a bath" to the spiritual level.
But it also had a practical side to it. At that time, people did not know about germs and dangerous micro-organisms but they were seeing the effects of touching dead bodies or bodily fluids, so they made cleanness mandatory in many levels for safety reasons.
Miasma was believed to taint not only the individual responsible but also anyone who came into contact with them or the polluted environment. (Basically, like a virus. Because those people were trying to protect themselves from viruses so they made such rules, just to be safe) This pollution disrupts the natural and divine order, and must be purified through specific rituals called to restore purity and harmony. A priest's murder could bring a plague upon a city, necessitating ritual cleansing with water, burning fragrant substances, or sacrifices.
Λύμα / Lyma
"Lyma" is "dirty waste/sewage water" in Greek. Lyma is the everyday kind of physical dirt or impurity that all people accumulate through normal life. More specifically, it's the dirty water/fluid that contains all that dirt. This could be your sweat, or the water after you take a bath.
To get rid of lyma, the ancient Greeks used basic cleansing rituals such as washing the body with water, bathing, and sometimes using soap or fragrant oils. This kind of purification was a routine part of life, helping to maintain physical cleanliness and by extension spiritual well-being. Unlike the complex rituals needed for miasma, cleansing lyma was a regular, simpler process done through washing and everyday hygiene practices.
I've found two posts that explain miasma and lyma in more detail. This post & this post.
(OP's blog is archived. When I can, I'll also paste the most useful info here, in case the links ever get deleted.)
I saw some other helpols that were a bit confused on the subject too, so I compiled this post from my personal notes and recent research to try and help .
lmk if anything is inaccurate or incorrect, and take this with a small grain of salt, as I'm fairly new too ^^ ( also because some post author's do include notes that some of their information is personal interpretation, so do keep that in mind )
additional note: the information here is sorted in order from naturally occurring / least severe "pollution" ( lyma ) to intentional, most severe ( agos ).

intro:
✦ in helpol, there are 3 concepts under the umbrella of spiritual pollution — lyma, miasma, and agos [ 3 ]
✦ to some, humans are seen as "naturally pure" beings, but as living, mortal creatures, spiritual dirt can cling to human beings and make them "impure" [ 3 ]
~ ✦ ~
lyma
lyma ( λῦμα ) - often refers to daily physical and spiritual dirt [ 4 ]
✦ lyma ( which is literally dirt that's washed away with water ) is what needs to be washed away before interacting with the gods [ 2]
✦ lyma means "something to be washed away", and is generally just physical dirt [ 3 ]
not a big deal when it comes to spiritual matters, but it's still best to be free of it when interacting with / approaching the gods [ 3 ]
✦ can be removed by handwashing or bathing [ 4 ]
✦ can also be gained by / through: [ 3 ]
childbirth
s*x
interaction with the dead
funerals
~ ✦ ~
miasma
miasma - spiritual pollution that gathers from death, murder, and generally all things that are unclean and immoral [ 1 ] or being around someone that has done such things
✦ miasma isn't something that everyone has to worry about, as it isn't just "pollution", but "defilement" that's incurred only when you've acted grossly outside of religious / moral norms [ 2 ]
as a result, it isn't something to fret over for most people [ 2 ]
✦ historically, miasma can be attracted / contracted by: [ 5 ]
participating in s*xual acts ( including kissing )
coming in contact with oxygenated blood
death or death in the home
birth ( mother and baby are miasmic for three days after postpartum and should be cleansed on day five )
murder / manslaughter ( not including blood spilled in battle )
sickness
✦ a / n: miasma is not to be confused with concepts of western origin ( i.e. sin in monotheism ), and there is no damnation attached to miasma
~ ✦ ~
additional info on miasma ( from @ sisterofiris )
✦ unlike lyma, miasma is not everyday spiritual pollution, and from this post, op researched and found that there weren't any texts where "a regular person purifies themselves of miasma before a ritual" [ 7 ]
all of the attested purifications of miasma are "expiatory rituals designed for criminals" specifically
✦ in ancient texts, miasma has the following causes: [ 7 ]
murder ( the most common )
murder of a family member
murder of fellow citizens
murder of animals ( only in Plutarch )
abandonment of a person to death
eating human flesh
incest, both contemplated and acted upon
adultery
refusal of suppliants
crime against a member of the priesthood
dedication of plunder taken from Greek people to the Greek gods
taking offerings from temples
death in a sacred space
non-specific crime
using bad language ( only in Charondas )
✦ "in the above contexts, miasma is often coupled with the words": [ 7 ]
ἀσεβής ( impious )
ἀκαθαρός ( impure )
ἀνόσιος ( unholy )
✦ It’s also worth noting that there are no mentions of miasma in the poetry of Homer or Hesiod; its earliest appearance is in Aeschylus’ plays [ 7 ]
✦ the only causes that overlap with modern understanding to some extent are: [ 7 ]
natural death and funerary rites
pollution associated with birth and death ( "mentioned by Diogenes Laertius in the phrase “death, birth and all miasma”, though it should be clarified that this is in relation to Pythagoreanism, not to the mainstream cult" )
✦ tl;dr: according to ancient texts, miasma is not a "morally neutral and inherently human occurrence [ 7 ];
its most normal cause is death, and possibly also birth, but more commonly, miasma is caused by ( according to Ancient Greeks ) severe physical impurity and by crime ( specifically, crimes against another person, and especially of the same family or social group, and crimes against the gods )
✦ a/n: this post also emphasizes the difference between lyma and miasma, and reiterates that lyma is simply translated as "dirt", and is the natural form of spiritual and physical pollution that miasma is often confused with; it also does a good job of going into how the confusion / misunderstandings began in the modern helpol community, so consider giving the rest of the post a read !
from Homer onwards, lyma is what people purified themselves of before ritual, not miasma
~ ✦ ~
agos
agos - a cursed state, and the most extreme form of spiritual pollution [ 3 ]
✦ this state is not easy to obtain, however: [ 3 ]
you will be in a state of extreme miasma if you commit a horrible act ( i.e. murder ) [ 3 ]
however, if the gods notice your crime and get enraged ( which isn't usually easy to do ), the miasma evolves into agos [ 3 ]
✦ miasma is a natural consequence of heinous acts, but agos only comes from the wrath of the gods, and is both a big deal + difficult to remove [ 3 ]
✦ fortunately, unless you're a horrible person who commits heinous acts, you don't have to worry about agos [ 3 ]
✦ agos is relatively "enhanced" compared to miasma — miasma is the result of heinous acts, while agos is intentional on the gods' part [ 6 ]
agos means 'curse', 'pollution', or 'abomination', and comes about as a result of deliberate acts; the term is associated with hostile spirits, land spirits, and violent death [ 6 ]
agos is very difficult ( if not impossible ) to cleanse, and can involve divine wrath [ 6 ]
often, it's the Erinyes that preside over those in a state of Agos
✦ historically, things that cause a state of Agos are: [ 6 ]
having s*x in a temple
temple robbing ( altars included )
murder
bloodshed in a temple or on sacred grounds
broken xenia
refusal to properly bury a family member or soldier ( even enemies )
killing someone that's under a god(s)' protection
offering human blood to the gods
broken oaths to a god
hubris
✦ consequences of Agos can be: [ 6 ]
ruination of life
suffering
harm to others
exile from the gods
✦ resolving agos means appealing to the gods, and can be through sacrifice, hardship, and offerings [ 6 ]
agos is often impossible to resolve, however
