Devotional Service is just like a seed sown in the heart of a living entity and if he goes on hearing & chanting, that seed fructifies, just as the seed of a tree fructifies with regular watering. Thus the spirtitual plant of devotional Service grows gradually.
It is Krishna’s desire that we should meet together and cooperate for the cause of Krishna consciousness movement which is so badly needed throughout the world. — Srila Prabhupada.
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,
Krishna takes charge of anyone who surrenders to Him in helplessness.
Srimad Bhagavatam 3.26.7,
Every person who has taken birth in this material world is destined to meet death, which is simply a matter of changing bodies, but no one except the Krishna conscious person knows where he will be going after this change of bodies.
