Jai Sri Ganesha,
The definition of Atman is not possible for anyone, one may define the ParamAtaman but the Atman, Atman differs from the Atman is the truth of the time and the ages,
Truthful soul embodied in cult with life for the journey of the planet in spirit with pilgrimage,
Soul in truth with an invariant pitch of ego visits the planet to explore it in varying chapters that concern self and the truth,
But Atman that lack of essential truth manifests to create chaos on the planet that poses challenges to fellow beings for a hidden cause,
May Lord bless all,
Thanka, please
