TRANSLATION

After hearing from the sun and moon demigods about Rahu's attack, the Supreme Personality of Godhead, Visnu, engages His disc, known as the Sudarsana cakra, to protect them. The Sudarsana cakra is the Lord's most beloved devotee and is favored by the Lord. The intense heat of its effulgence, meant for killing non-Vaisnavas, is unbearable to Rahu, and he therefore flees in fear of it. During the time Rahu disturbs the sun or moon, there occurs what people commonly know as an eclipse.
