7 Dimensions Existential Universes:
ॐ भूर्भुवः स्वः जनः महः तपः सत्यम् --
ॐ Is the Brahman the Potential the manifest and the unmanifest. As is in parts, in the aggregate / collective, The Total, Ultimate.
भूः is the manifestation the space and matter as is known through sense-organs.
भुवः is the sentience the organism where the sense of me and not me is yet to evolve. The same could be called Prakriti / the plant and the animal kingdom.
स्वः is the sentience where the sense of 'me' and 'other than me' has emerged out, where the mass of matter is named as the 'me' and the 'other than me' as the 'my world'.
जनः Where the 'other than me' is categorized in sentient and insentient objects. The World respectively of beings, things and animals.
महः Where there are bigger, gigantic living beings who have many different enormous individual qualities, of the either kind of the physical, mental, intellectual or the Super normal.
तपः When a normal being has attained this level of gradual evolution from the mundane to the Super normal and has realized the तपः / austerities and penance are the very nature of existence.
सत्यम् : Where one merges into the foundation and the very source from where the 7 spaces emerge out, exist and finally and ultimately dissolve into. The Imperishable ॐ where the 7 Spaces (Universes) are no more, nor the individual.
