Bhasya by Srila Bhakti Vinod Thakur

asat-sanga tyaji’ sadhu-sanga kara bhai
pritira laksana chhaya vichari’ sadai [1]

Brother, give up bad association, associate with the sadhus, and always engage in the six exchanges of love.

dana-graha sva-sva-guhya jijnasa varnana
bhunjana bhojana-dana sangera laksana [2]

Giving and accepting gifts, asking about and describing confidential matters, and eating and distributing food are the characteristics of such association.

Piyusa-varsini-vrtti by Srila Bhakti Vinod Thakur

Association with non-devotees is unfavourable to devotion and should therefore be rejected. The association of pure devotees, which purifies the effects of association with non-devotees, is necessary for persons engaged in devotional practice. Love, in the form of association with sadhus that is nourishing to devotion, is prescribed in this fourth verse. Lovingly offering devotees things that are necessary for devotees, accepting things given by devotees, speaking about confidential matters with devotees, asking devotees about confidential matters, eating food given by devotees, and feeding devotees—these are the six characteristics of real love. Through them, one should serve the sadhus.
