The following is the conclusion of a lecture given by His Divine Grace A.C. Bhaktivedanta Srila Prabhupada on January 11th ,1974 in Los Angeles. (Śrīmad-Bhāgavatam 1.16.16)
So this Kṛṣṇa consciousness movement, there are so many things to learn. And when practically one learns everything—not everything; as far as possible, perfection—then his position is janma karma me divyaṁ yo jānāti tattvataḥ [Bg. 4.9]. Anyone who learns about Kṛṣṇa, His janma... He has no father, but He is accepting a father. Therefore janma. Janma means birth. When there is birth, there must be father and mother. So when Kṛṣṇa takes His birth, appears, as a son, so there must be father and mother. But who can be His father and mother? His devotee. Because His business is with the devotees; with no other else. When He wants father and mother, the devotee must be father... Even when He wants some enemy, the devotee will become His enemy, what to speak of father and mother.
Therefore He is all-attractive. He is as much attractive to His father and mother, similarly, He is attractive to the small calf. You have seen the picture. Kṛṣṇa is embracing. Kṛṣṇa is not simply embracing Rādhārāṇī or the gopīs. He is embracing the insignificant animal, calf. Therefore He is all-attractive. And when the calf goes to Kṛṣṇa... This is described in the Kṛṣṇa book, how all the cows and calves were so much, I mean to say, attached to Kṛṣṇa. That is Vṛndāvana. Everyone is attached to Kṛṣṇa. It doesn't matter whether he is human being or plant or trees or water or animal or the land or the flowers or the fruits. Whatever there is, they are all attracted to Kṛṣṇa.
