Please accept my humble obeisances, Maharaja! About to what chakra's Tesla converter reaches. This is what I think-: the lowest frequencies would affect the root chakra and higher frequencies, I would like to think to the crown chakra, but vedic knowledge would in my view support the thought that the last two chakras would not be in material world, and not ether, in that scenario. I'm just thinking why else the planets would have same numeric quantities and so on... as the chakras ........

Hare Krishna . May Srila Prabhupada be glorified all around the world

HpS - When the top Chakra is described as Brahma randra we are thinking that it is refering to Brahma loka within this material world.  Heart chakra is nice, no?  This Earth level which is very nice for spiritual progress. Brahmaloka is very good for playing chess in four dimensions.
