Meaning of Surrender

I heard

Surrender means to GIVE

There is always an understanding that Surrender means to GIVE UP

BUt actually Surrenders means to GIVE oneself to LORD

When one submits to Lord fully that is surrender

Then he has nothing to worry or Fear because the lord will take care of him.

(9) Atma-nivedanam. The word Atma-nivedanam refers to the stage at which one who has no motive other than to serve the Lord surrenders everything to the Lord and performs his activities only to please the Supreme Personality of Godhead. Such a devotee is like a cow that is cared for by its master. When cared for by its master, a cow is not in anxiety over its maintenance. Such a cow is always devoted to its master, and it never acts independently, but only for the master's benefit. Some devotees, therefore, consider dedication of the body to the Lord to be atma-nivedanam, and as stated in the book known as Bhakti-viveka, sometimes dedication of the soul to the Lord is called atma-nivedanam. The best examples of atma-nivedanamare found in Bali Maharaja and Ambarisa Maharaja.

Atma-nivedanam is also sometimes found in the behavior of Rukminidevi atDvaraka.
