Distribution of books and magazine is our most important activity. Without books, our preaching has no solid basis.
The Lord is reciprocally respondent to His devotees.
Srimad Bhagavatam 1.2.17,
Every word, Every Sloka, Every Book of Vedic Literature… The more you preach, the more you distribute, the more it weighs.
Whenever there is congregational chanting of the holy names of the Lord, Gaura Narayana, the Supreme Personality of Godhead in His incarnation as Lord Chaitanya, immediately appears and is worshiped by sankirtana-yajna.
Srimad Bhagavatam 4.30.36,
