The holy name of Krishna is so attractive that anyone who chants it — including all living entities, moving and nonmoving, and even Lord Krishna Himself — becomes imbued with love of Krishna. This is the effect of chanting the Hare Krishna maha-mantra.
Chaitanya Caritamrta, Antya Lila 3.268,
Srila Prabhupada
The chanting of the holy name of Krishna expands the blissful ocean of transcendental life. It gives a cooling effect to everyone and enables one to taste full nectar at every step.
Sri Chaitanya Caritamrta,
Antya Lila, 20.12
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.
Chaitanya Caritamrta,
Madhya Lila 21.136
The moonlike face of Krishna is the reservoir of nectarean songs and the abode of His flute.
