Sat-sanga required-Lec 1/8/'75; SB 6.1.49

[Cintamani]

So our Krsna consciousness movement is to raise a person from ignorance to knowledge. That is the whole scheme of Vedic literature: to deliver a person. Krsna says in the Bhagavad-gita about the devotees -- not for all -- tesam aham samuddharta mrtyu-samsara-sagarat [Bg. 12.7]. Another:
tesam evanukampartham
aham ajnana-jam tamah
nasayamy atma-bhavastho
jnana-dipena bhasvata
[Bg. 10.11]
For special, for the devotees... He is situated in everyone's heart, but a devotee who is trying to understand Krsna He helps. He helps. To the nondevotees, they have no concern with the... They are just like animal -- eating, sleeping, sex life and defense. They do not care for anything, to understand God or his relationship with God. For them, they think there is no God, and Krsna also says, "Yes, there is no God. You sleep." That's all. Therefore sat-sanga required. This sat-sanga, satam prasangat. By the association of devotee we awaken our inquisitiveness about God. Therefore the centers are required. It is not unnecessarily we are opening so many centers. No. It is for the benefit of the human society.
