Association of material attachment means implication in this material conditional life. So one has to make association with devotees. Satāṁ prasaṅgād mama vīrya-saṁvido. One can understand about God only in association of devotees. Therefore we are advocating this Kṛṣṇa consciousness movement, society. Actually, you'll find, one who comes to this Society, by associating a few days, a few weeks, he becomes conscious and he comes forward for initiation and further advancement.
So this association is very important. And those who are conducting different centers and temples, they should be very responsible men. Because everything will depend on their sincere activities and character. If they are insincere, then that will be not be effective. One may come and associate with us, but if we are insincere, then it will be not be effective. But if the devotees are sincere, anyone who will come in contact with a devotee, he'll change. That is the secret.
