Simply read my books and repeat what I have written then your preaching will be perfect.
BOOKS ARE THE BASIS
"There is no literature throughout the universe like Srimad Bhagavatam. There is no comparison. There is no Competition. Every word is for the good of human society. Somehow or other, if a book goes in someone's hand, he will be benefited… Therefore we are stressing so much, 'Please distribute books, distribute books, distribute books'" – Srila Prabhupada.
Any person who is chanting the holy names of Krishna (Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare) in course of chanting without offenses feels some transcendental pleasure and very quickly becomes puriﬁed of all material contamination.
Bhagavat Gita 9.2,
It is the duty of all parents to make their child Krishna conscious so that the fortunate child may not have to take birth in the material world again.
