Atma or Brahman is considered as not having any properties(Nirguna). Then why the karma that lead to reincarnation attaches to it? Is Pind-deha has any connection with this?
It's due to string theory, everything is frequency after the smallest matter partical atom , quarks. So the smallest known thing in any object will be a form of frequency only, that's the reason this frequency resonance according to act (karma) and indirectly karma effect you me mostly. But some time you can also see the instant karma as well.
