SB 11.13.39
aham yogasya sankhyasya
satyasyartasya tejasah
parayanam dvija-sresthah
sriyah kirter damasya ca
Translation:
O best of the brahmanas, please know that I am the supreme shelter of the yoga system, analytic philosophy, virtuous action, truthful religious principles, power, beauty, fame and self-control.
Purport:
According to Srila Sridhara Svami, the synonymous words satyasya and rtasya refer to, respectively, the proper or virtuous execution of religious principles and a convincing presentation of religion. Srila Visvanatha Cakravarti Thakura points out that the sons of Brahma were struck with wonder at the presentation of the Supreme Personality of Godhead and were thinking, “What wonderful knowledge we have just heard.” The Lord, recognizing their astonishment, spoke this verse to confirm their understanding of Him.
