Jai Sri Ganesha,
There is no scientific way to reach at the truth of Atman, Yet Atman exist in both format,
Animate and Inanimate,
Shadow alone could be the physical identity of Atman yet it manifest through body whichever body it may be,
All beings are referral truth of Atman, yet Atman is above the horizon of Body, source of Atman is eternity, it manifest from and merge in,
May Lord bless all,
Thanks please
