Atman seeking Union with Divine One. Applicants should inquire within...
Who am "I"? Am I my name? My possessions? My body? My reputation? My friendships? My wealth? My ideas? My education? My sufferings? My joys? My dreams? Yet, all these things will change over time. All my posessions will turn to dust. My good reputation will fall into disrepute. My name will become tarnished. My relationhips will fall apart. My body will age, slowly wear out, and dissolve. If I am nothing more than my body, my ego, then who I am is a fleeting thing indeed.... yet... is there something more to "me"? (and you too!?)
This is the "self-inquiry" which Shankara has shown is the most fundamental quest
