Listen to another great mystery unknown to many. The celestials do not eat the libations on occasions of Shraddhas and rites in their honour or on occasions of those rites which are performed on ordinary lunar days or on the especially sacred days of the full moon and the new moon, if they see a woman in her menses or one who is the daughter of a mother suffering from leprosy.
इदं च परमं गुह्यं सरहस्यं निबोधत। श्राद्धकल्पे च दैवे च तैर्थिके पर्वणीषु च॥ रजस्वला च या नारी वित्रिकापुत्रिका च या।
