Most Confidential Knowledge!

Verse 1.5.30: Krishna is telling in the Bhagavad-gita to Arjuna, that this knowledge is most confidential.

Confidential: You are not this body, you are a spirit soul
More confidential: God is a person, He has a impersonal form pervading everywhere as Brahman, as Paramatma He is in everyone
Most confidential knowledge: We can attain to the Supreme Personality of Godhead, but pure devotional service. This is done by unalloyed pure devotional service.

Those who are bhaktivedanta's have this knowledge. Srila Prabhupada, he was given the title Bhaktivedanta, he know how to execute this pure knowledge and taught it also to so many many many of us.

We have to continue to execute the order of our spiritual master, at all times. Srila Prabhupada, during his vanaprastha time did not even have proper clothes, but still he continued just to serve his spiritual master.
