It is sometimes argued that the sons of King Sagara were burned to ashes by the fire emanating from the eyes of Kapila Muni. This statement, however, is not approved by great learned persons, for Kapila Muni’s body is completely in the mode of goodness and therefore cannot manifest the mode of ignorance in the form of anger, just as the pure sky cannot be polluted by the dust of the earth.
