What does it mean to surrender to God?
Offering body, mind, speech and ego
Complete surrender means body, mind, speech and ego are all placed at God's feet. The body is surrendered when every action is done for his pleasure, and only dharmic conduct can be offered to God.
The form of complete surrender is that body, mind, speech and ego are offered at God's feet. The body is offered when all our actions begin to be only for God's pleasure.
