I Will Take You To The End.

Surrender does not mean mere prostration

Surrender does not mean mere prostration and service to the Guru. It means complete surrender of everything, including the body and mind, with the conviction that the body belongs to the Guru and exists merely to serve Him. 

I am dependent on him who thinks and hungers after Me

I am dependent on him who thinks and hungers after Me and who does not eat anything without first offering it to Me. He who thus comes to Me thinks as one with Me, just as the river gets to the sea and becomes merged with it. So leaving out pride and egoism and with no trace of them, you should surrender yourself to Me who am seated in your heart.

A guide (Guru) is always necessary to show right way

Relying on your own cleverness, you missed your way. A guide (Guru) is always necessary to show right way.

Surrender does not mean mere prostration

Surrender does not mean mere prostration and service to the Guru. It means complete surrender of everything, including the body and mind, with the conviction that the body belongs to the Guru and exists merely to serve Him.
