the astral (astral body and mind)

the causal (no astral body but still mind)

(three other planes)

the Brahm (of Brahmand)

Sach Kahnd (pure and only soul, home)


(my explinations about the planes/realms isn't 100% right, but at this time i can't get everything on one line)

in the astral realm alone are allready manymany worlds. through psychedelics you can achieve going to the astral plane, but in your way to pure planes and losing body and mind so in the fine planes only soul stays, astral is just the beginning. there are uncounterable many dimensions, but of more heavy and grove shabd/energy. every chakra has it's own worlds. we need a master (like shaman in rituals) not to get lost in worlds.
