Understand that the physical/ego does not exist and finally be free.
Sometimes we worry too much about trying to get rid of the ego, about ignoring the physical (or 3D, if you prefer), we try to reflect for hours about the physical, seeking to finally detach ourselves from it...But if you know that never existed, then what exactly are you trying to get rid of? There's no one, there's nothing, so what are you trying to let go of?
There is no ego, no physical form, there is no human being, there is no human experience. Stop worrying about not being, about ceasing to identify with the ego, about ceasing to identify with the physical, like... you're already none of that! Sometimes we worry too much about "destabilizing" the physical world so that something finally works, but who notices this lack? There is no lack, no one notices this lack, the lack is an illusion.
People struggle to manifest their dream appearances, but why would that be difficult? You don't have a body, you ASSUMED to have a body (you = consciousness), so why would you have difficulty assume a "new" body?
Some people think they can't manifest S/P, but if there isn't another person separate from you, nothing exists outside of consciousness, and you have ACCEPTED the existence of that person, then why would it be difficult to manifest them?
Some people struggle to shift, but shifting itself doesn't exist (since shifting is a name we give to something as natural as breathing, but people treat it as something abnormal), if reality itself doesn't exist, if the ego doesn't exist, and it's all a matter of changing your focus... then why do you think you would have difficulty?
Some believe that consciousness is not in everything, but rather within the body, but that doesn't make sense, The body doesn't exist, so how can consciousness reside within this illusory body? The human being don't exist, so how can anything reside within them?
The ego is a creation of the mind, and the mind does not exist; the mind is not a real entity. The mind itself is the name we give to a collection of thoughts, and thoughts are not real, thoughts are not fixed, So, therefore >> It doesn't exist, it can't affect me.
Think of a lucid dream; it occurs when you realize it's not real, and then you can control it however you want. And it's not something you have a huge process to "awaken" to in the dream, you simply perceive it, and from there you control everything without limits. Why do you think it would be different with "this reality"? Since nothing changes from the dream to the physical reality, after all, the basis and the creator are the same: the consciousness.
There are accounts that tell you to demonize the ego, to treat it like crap and whatnot, but where will that get you? And what do you have to ignore when you CAN'T IGNORE SOMETHING THAT DONT EXISTS?
