The transcendental body of Krishna is very sweet, and His face is even sweeter than His body. But His soft smile, which has the fragrance of honey, is sweeter still.
Madhya Lila 21.136
Anyone whose work is not meant to elevate him to religious life, anyone whose religious ritualistic performances do not raise him to renunciation and anyone situated in renunciation that does not lead him to devotional service to the Supreme Personality of Godhead must be considered dead, although he is breathing. – Srimad Bhagavatam, 03.23.56.
There are many incarnations, who are compared to lamps but the first lamp, the original Personality of Godhead, is Krishna.
