Sūta said: In Kṛta yuga, the sustenance of people was from taking liquids; in Tretā yuga from domestic trees. But this was discontinued during the subsequent ages. The same occurred in regard to the untimely intercourse, during the menstrual discharge, due to lust of men. O Brahmins, so barley and other plants of the village and forest as well as the fourteen types of medicinal herbs were cultivated untimely and destroyed, as in the case of sexual intercourse during the menstrual period due to the passion of men.
