5.5.1

parāśara uvāca:
vimukto vasudevo 'pi nandasya śakaṭaṃ gataḥ
prahṛṣṭaṃ dṛṣṭavān nandaṃ putro jāto mameti vai //

WHEN Vasudeva was set at liberty, he went to the waggon of Nanda, and found Nanda there rejoicing that a son was born to him. Vasudeva spake to him kindly, and congratulated him on having a son in his old age. "The yearly tribute," he added, "has been paid to the king, and men of property should not tarry near the court, when the business that brought them there has been transacted. Why do you delay, now that your affairs are settled? Up, Nanda, quickly, and set off to your own pastures; and let this boy, the son whom Rohińí has borne me, accompany you, and be brought up by you as this your own son." Accordingly Nanda and the other cowherds, their goods being placed in their waggons, and their taxes having been paid to the king, returned to their village.
