Books are the basis! The whole movement of Hare Krishna revolution or ISKCON is expanding by distribution of the transcendental books. The knowledge in these books are unlike mundane knowledge that we daily read in novels, newspapers, magazines, etc. Rather, it is non-different from Krishna Himself being based on The Bhagavad Gita, Shrimad Bhagvatam and other Vedic literatures. This in fact is the secret behind the movement’s outspread like a wildfire since its beginning, for truth works!
Book reading and book distribution hence are most purifying activities. By reading and hearing this knowledge not only one establishes ones intelligence, but also purifies ones contaminated heart.
yathaidhāṁsi samiddho ’gnir
bhasma-sāt kurute ’rjuna
bhasma-sāt kurute tathā
“As a blazing ﬁre turns ﬁrewood to ashes, O Arjuna, so does the ﬁre of knowledge burn to ashes all reactions to material activities.”(BG 4.37)
Therefore the practitioners of bhakti yoga lay a lot of emphasis on hearing the message of Shrimad Bhagvatam daily and apply the same in their day to day activities to find a transformed existence. Therefore, just by hearing in association of devotees one can find the spiritual upliftment. The immediate effect of hearing the transcendental knowledge is to preach it out to lost people in general in the form of book distribution and speaking on streets and programs, just in order to please Krishna.
ya idaṁ paramaṁ guhyaṁ
bhaktiṁ mayi parāṁ kṛtvā
mām evaiṣyaty asaṁśayaḥ
“For one who explains this supreme secret to the devotees, pure devotional service is guaranteed, and at the end he will come back to Me.” (BG 18.68)
In other words, the more we give Krishna, the more we get Krishna!
