Translation:
Thereafter, O Mahārāja Parīkṣit, as required according to the scheduled round of His pastimes, Kṛṣṇa returned in the evening, entered the house of each of the cowherd boys, and engaged exactly like the former boys, thus enlivening their mothers with transcendental pleasure. The mothers took care of the boys by massaging them with oil, bathing them, smearing their bodies with sandalwood pulp, decorating them with ornaments, chanting protective mantras, decorating their bodies with tilaka and giving them food. In this way, the mothers served Kṛṣṇa personally.
