The guru was asked, "What is enlightenment?" 
Ramakrishna replied, "You are asking this as a drop of water asks the ocean, "Who am I?" 
The ocean says, "Come closer, jump in." 
The droplet of water jumps in and the ocean asks, "Now what are you?" 
The water replies, "I am That. I am You, and yet I am exactly the same as before."
