Purport
Both Śrīdhara Svāmī and Viśvanātha Cakravartī Ṭhākura explain the term gāyatraṁ vratam as the vow of brahmacarya, or celibacy in student life. Kṛṣṇa and Balarāma were playing the part of perfect students on the path of self-realization. Of course, in the modern, degraded age, student life has become a wild, animalistic affair filled with illicit sex and drugs.
