"Prajapati (the lord of the year) felt love towards his own daughter, the sky some say, the dawn others. Having become a stag he approached her in the form of a doe. The Gods saw him. "A deed unknown Prajapati now does." They sought someone to punish him; they could not find anyone among them to do this. So they brought their most terrible forms together in one being. To him (Rudra) the Gods said, "Prajapati here has done a deed unknown; pierce him." Having aimed at him he pierced him; being pierced he flew upwards; him they call "the deer" (mriga). The piercer of the deer is he called by that name (mrigavyadha). The female deer is Rohini; the threepointed arrow is the constellation of the three-pointed e arrow."
