Bhishma said In the month of Margashira, when the inoon comes in conjunction with the asterism called Mula, when his two feet are united with that very asterism, O king, when Rohini is in his calf, when his knee-joints are in Ashvini, and his thighs are in the two Ashadas when Phalguni makes his anus, and Krittika his waist, when his navel is in Bhadrapada, his ocular region in Revati, and his back on the Dhanishthas, when Anuradha makes his belly, when with his two arms he reaches the Vishakhas, when his two hands are indicated by Hasta, when Punarvasu, O king, makes his fingers, Ashlesha his nails when Jyeshtha makes his neck when Shravana makes his ears, and Pushya his mouth when Svati is said to make his teeth and lips, when Shatabhisha is his smile and Magha his nose, when Mrigashiras is known to be in his eye, and Chitra in his forehead, when his head is in Bharani, when Ardra forms his hair, o king, the vow called Chandravrata should be taken in hand. Upon the termination of that vow, gifts of clarified butter should be made 10 Brahmanas conversant with the Vedas.
