bhuvana jnaananam suurye sanyamaat (Yoga Sutras, III.26)
By sanyama [perfect regulation of thought via dharana, dhyana, and samadhi) on the sun, knowledge of the worlds.
Ammachi, Karunamayi, even the Hymn to the Ganga refer to the three worlds.
I think it’s interesting that by the Sun, one may have knowledge of these worlds. Not just our solar system.
The “three worlds” makes sense from an advanced physics view, that there is one “brane” to the side of us, one that we are in, and one to the other side of us.
I am also thinking of the Surya Siddhanta (“Abilities from the Sun”, a grand mathematical treatise on the solar system) but I think this sutra actually goes beyond that, from the world, to the three worlds (the bhuvana or the planes of existence). I like that word, bhuvana, coming from bhu – to be and -vana, a place to dwell, often used for forests.
I have absolutely no cognitive experience of the three worlds and can’t comment further.
