uttamah purushas tv anyah paramatmety udahrtah। yo loka-trayam avisya bibharty avyaya ishvarah॥ 15.17 ॥

Sri Krishna said: O Arjuna, Besides these two, there is the greatest living personality, the God Soul, the imperishable Lord Himself, who has entered the three worlds and is maintaining them.

yasmat ksharam atito ’ham aksharad api cottamah। ato ’smi loke vede cha prathitah purushottamah॥ 15.18 ॥

Sri Krishna said: O Arjuna, Because I am transcendental, beyond both the fallible and the infallible, and because I am the greatest, I am celebrated both in the world and in the Vedas as that God Person.

yo mam evam asammudho janati purushottamam। sa sarva-vid bhajati mam sarva-bhavena bharata॥ 15.19 ॥

Sri Krishna said: O Arjuna, Whoever knows Me as the Supreme God, without doubting, is the knower of everything. He therefore engages himself in full devotional service to Me.
