sanat-kumāraṁ bhagavantam ekam
ārādhya bhaktyālabhatāmalaṁ taj
jñānaṁ yato brahma paraṁ vidanti
The word vidanti refers to one who knows something or enjoys something. When a person is properly instructed by a spiritual master and understands transcendental bliss, he enjoys life. As stated in Bhagavad-gītā (18.54), brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati: when one attains to the Brahman platform, he neither hankers nor laments, and he actually partakes of transcendental, blissful enjoyment. Although King Pṛthu was an incarnation of Viṣṇu, he nonetheless taught the people in his kingdom to take instructions from a spiritual master who represents the disciplic succession. Thus one can become fortunate and enjoy a blissful life even within this material world. In this verse the verb vidanti is sometimes taken to mean “understanding.” Thus when a person understands Brahman, or the supreme source of everything, he enjoys a blissful life.
