Mrgashiras is a nakshatra (one of 27 800 arcminute divisions of the zodiac) not a constellation per se. The nakshatras are however associated with specific stars. Mrgashiras with Gamma Orionis (the "right shoulder" I think?" The next nakshatra Ardra (Alpha Orionis or Betelgeuse) is also in Orion. A problem in all religions is how to explain the presence of evil in the world. One answer from the Vedas is that the creator, Prajapati (the antecedent of Brahma in later Hinduism) first created a daughter but then united with her to produce the human race. She fled from him in various female animal shapes but he became the male of the species each time thus creating all the animals. The Gods looked upon this with dismay and sent Rudra (the antecedent of Shiva. He is often portrayed as a bow-armed hunter.) to punish Prajapati for the sin of incest. Rudra hunted down Prajapati when he was in the form of a stag and his daughter a doe and pierced (castrated?) him with an arrow. Some tellings of this story include astronomical symbolism. Rudra is Sirius. Prajapati is Orion. The arrow is "Orions belt" and the daughter is the nakshatra Rohini (Alpha Taurii or Al Deberan.) Rohini means deer in Sanskrit.
