Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
While mother Yasoda was churning butter, Lord Krsna, desiring to drink the milk of her breast, appeared before her, and in order to increase her transcendental pleasure, He caught hold of the churning rod and began to prevent her from churning.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Krsna was sleeping within the room, and as soon as He got up, He became hungry and went to His mother. Wanting to stop her from churning and drink the milk of her breasts, He stopped her from moving the churning rod.
