[Nārada Muni had spoken of a swan. That swan is explained in this verse.] The Vedic literatures [śāstras] vividly describe how to understand the Supreme Lord, the source of all material and spiritual energy. Indeed, they elaborately explain these two energies. The swan [haṁsa] is one who discriminates between matter and spirit, who accepts the essence of everything, and who explains the means of bondage and the means of liberation. The words of scriptures consist of variegated vibrations. If a foolish rascal leaves aside the study of these śāstras to engage in temporary activities, what will be the result?
