THE ESSENCE

The Supreme Personality of Godhead is known as bhava-grahi janardana because He takes only the essence of a devotee's attitude.

If a devotee sincerely surrenders, the Lord, as the Supersoul in everyone's heart, immediately understands this. 

Thus even though, externally, a devotee may not render full service, if he is internally sincere and serious the Lord welcomes his service nonetheless. 

Thus the Lord is known as bhava-grahi janardana because He takes the essence of one's devotional mentality.
