Bhagavad Gita: Cause of all causes [Knowledge of the Absolute (Text 19 Chapter 7)]

sri-bhagavan uvaca

bahunam janmanam ante
jnanavan mam prapadyate
vasudevah sarvam iti
sa mahatma su-durlabhah

(Knowledge of the Absolute, Text 19 Chapter 7)

Meaning: After many births and deaths, he who is actually in knowledge surrenders unto Me, knowing Me to be the cause of all causes and all that is. Such a great soul is very rare.

*** In this body there are powers of speaking, of seeing, of hearing, of mental activities, etc. But these are not important if not related to the Supreme Lord. And because vasudeva(God) is all-pervading and everything is Vasudeva(God), the devotee surrenders in full knowledge.
