"“The Apsaras Purvacitti was her Urvasi’s) sister. She thought, "My sister has been living among human beings for a long time. I shall meet her." (Even after) Coming to her, she could not meet her. She resided with the herd of sheep in her (Urvasi’s) possession because such was the appearance of old ladies. She assumed the form of a wolf and caused a violent stir up (in the herd of sheep). A young ram, still sucking its mother was tied to a foot of her (Urvasi’s) bed. She (Purvacitti) snatched it away. As it was stolen away, (Urvasi) wept, "My ram is stolen". Hearing it, the king jumped up. He approached her (Purvacitti). He met (came close to) her. Transformed as a female ichneumon, she went to him. She deprived him of his inner garment. She (Purvacitti) generated lightning. She (Urvasi) saw him naked in the light of the lightning. The king came and said, "I could not help; my ram had indeed disappeared."(2) (Urvasi said-) "I shall leave thee." (Pururava said-) "What is happened?" (Urvasi replied-) "I saw you naked." After her departure the king, with the harm already done, and suffering from grief, wandered. Brhaspati, son of Angiras said to him, "I shall cause you to perform the Sada sacrifice. I shall help thee in the wandering." Brhaspati made him perform the Sada sacrifice. After having returned from the Avabhrta (the king) saw her (Urvasi). The sons approached her and said, "Do thou take us there where thou are going. We are strong. Thou hast put our father, one of you two, to grief." She said, "O sons, I have given birth to you together. (Therefore) I stay here for three nights. Let not the word of the brahmana be untrue." The king wearing the inner garment lived with her for three nights. He shed semen virile unto her. She said, "What is to be done?" "What to do?", the king responded. She said, "Do thou fetch a new pitcher?" She disposed it into it. In Kurukshetra, there were ponds called Bisavati. The northern-most among then created gold. She put it (the semen) into it (the pond). From it (the banks of the pond) came out the Asvattha tree surrounded by Sami. It was Asvattha because of the virile semen, it was Sami by reason of the womb. Such is the creation of (Asvattha tree) born over Sami. This is its source. It is indeed said, "Gods attained heaven through the entire sacrifice." When the sacrifice came down to man from the gods, it came down upon the Asvattha (tree). They prepared the churning woods out of it; it is the sacrifice. Indeed, whichever may the Asvattha be, it should be deemed, as growing on the Sami (tree). When it is said, "Thou art Urvasi, Ayu and Pruvasas," one utters the names of the father and the sons. This may also be taken in general sense. After her departure, the king, with the harm already done, and suffering from grief, wandered. Brhaspati, son of Angiras said to him, "I shall cause thee perform the Aupasada sacrifice; thereby thy harm will disappear." Brhaspati, son of Angiras made him perform the Aupasada sacrifice. Thereby his harm disappeared. The Sadaupasada (sacrifices) are also known as Paururavasau. One who desires to obtain wealth, him should one cause to perform he Sada. In his sacrifice the Bahispavamana is in ten Stomas. ……."
