kapilo narado datto
tam anviyur bhagavata
ye ca tat-sevanotsukah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Great devotees, who were always engaged in the service of the Supreme Personality of Godhead, as well as the great sages named Kapila, Narada and Dattatreya, and masters of mystic powers, headed by Sanaka Kumara, all attended the great sacrifice with Lord Visnu.
