The king said—"It was yourself who commanded this food to be prepared". Vasishtha said—"By me, how could that have been". And being engaged in meditation again he found out the whole truth. Being pleased with the king he said—"The food to which I have doomed you shall not be your sustenance for ever; it shall be only so for twelve years". And the king, taking water in his palms addressed himself for cursing the sage but gave up his intention, being reminded by his queen Madayanti that it ill became him to imprecate a curse upon a holy teacher who was the guardian divinity of the family. Unwilling to throw the water upon the earth lest it should wither up the grain for it was filled with malediction and being equally unwilling to throw it up into the air lest it should blast the clouds and dry up their contents, he threw it upon his own feet. Scalded by the heat which was in the water on account of his angry imprecation the feet of the king became spotted black and white and he therefore obtained the name of Kalmashapāda (i.e. having spotted feet).
