Within the Hiryanyagarbha (golden womb) of Shree Bhagwati lies an amniotic sea which holds a resting Parambrahm, known as Visnu, the all pervasive. Him, and Bhagwan Siva, the auspicious, are present in the particles and matter that make up the amniotic sea, and brings something out of nothingness. HariHara is the same tattwa. Along with Shree Bhagwati. This is all the divine act of the Supreme.
(The formless is seen to be without a form. But in this concept, one can comprehend that the formless has Sagun forms that form the womb, the bearer, the mass that's in the womb(fetus), the amniotic sea that make up the cosmos, and the creation (Brahma). These entities are important for creation.
Parambrahm/Brahmin/The formless Supreme creates creation itself.
VisnuSiva, Vishnu Shiva can mean the auspicious that is pervasive. The auspicious that can be felt everywhere. The auspicious that is omnipresent and omnipotent.
That's maybe why it's said in the Vedas, that all creation made by Bhagwan is auspicious. Bhagwan's creation is indeed vast.
Visnu is shaant, as he's the preserver. The act of protecting and preserving must be done with a cool mind. Yet He can take his Ugra form when dharma is in danger.
Siva is Rudra (Raudra- meaning fierce)
As the destroyer of inauspicious entities, he takes a fiery form. Yet he's mostly seen in a shaant/calm/relaxed form. Meaning that peace is eternal. Anger shouldn't be used unneccerily.
Visnu takes his Padmanabham form, and Brahma arises from the lotus, creating the universe.
He's seated on a lotus, which represents peace, auspiciousness and intellect.
Once the Sahasrara chakra (the crown chakra, represented by a lotus) is opened, then the mind is open. And when the mind is open, then one can create, and absorb intellect.
Prabhu SadaShiva and his Shakti Bhavani (in the form of Parvati) completes each other. They're Prakriti and Purush.
MahaLakshmi and MahaVisnu's union is also sacred. She helps him in preserving the world.
Maa Saraswati and Brahma create the vast universe, and gave the gift of knowledge through Vedas, music, arts and Siddhis. Then Brahma made Jeevas (forms of life - people, plants, animals etc.) Then he made his manasputro and sent them to Earth(Prithvi), so that they can spread the knowledge of the Vedas and other things.
The devas, grahas, panchbhootas arise from them (Tridev/Tridevi) they were born from their effulgance. Then the divine entities made various forms of themselves just for the Jagat Kalyan (calling them Anshas, avatara, roopams, Angas.)
