"The whole system was that. Love exchange. I give you some service; you give me something, out of your love. Dadāti pratigṛhṇāti. Love means six symptoms. I give you something; you give me something. I give you something for eating; you also give me something for eating. Dadāti pratigṛhṇāti bhuṅkte bhojayate, guhyam ākhyāti pṛcchati (Upadeśāmṛta 4). If I am in trouble, I express my mind, I open my mind before you, and you also try to help me. These are the six signs of love. That is Vedic civilization—everything exchange of love. No business, mercantile."
(Srila Prabhupada Lecture, Los Angeles, June 22, 1972)
