Sri PBA Swami's Sarartha Deepikai:
Now the second part of the Charama shloka is explained.

In the first part of the shloka, the chetana's act was explained. In the second part, the act of the Lord, who is Himself the means, is told.

aham - I (the Lord) who am all knowing (omniscient), who am all powerful (omnipotent) and who am the goal (as He is the Lord).
