YV 5.2b

' They said, 'Let us choose a boon; let us obtain offspring from after the menses; let us enjoy intercourse at will up to birth.' Therefore women obtain offspring from after the menses, and enjoy intercourse at will up to birth, for that was what they chose as a boon. They took a third of his guilt, it became (a woman) with stained garments; therefore one should not converse with (a woman) with stained garments [5], one should not sit with her, nor eat her food, for she keeps emitting the colour of guilt. Or rather they say, 'Woman's food is unguent, and there fore one should not accept (from her) unguent, but anything else (can be accepted) at will.' The son born of intercourse with (a woman) with stained garments is accursed; (the son born) of intercourse in the forest is a thief; (the son born) of intercourse with a (woman) who turns away is shamefaced and retiring; (the son born) of intercourse with a woman bathing is fated to drown; (the son born) of one who [6] anoints herself has a skin disease; (the son born) of one who combs her hair is bald and feeble; (the son born) of one who anoints (her eyes) is blind; (the son born) of one who cleans her teeth has dirty teeth; (the son born) of one who cuts her nails has bad nails; (the son born) of one who spins is a eunuch; (the son born) of one who weaves ropes is unrestrained; (the son born) of one who drinks from a leaf is drunken; (the son born) of one who drinks from a mutilated (vessel) is mutilated. For three nights he should keep a vow and should drink from his hand or from a perfect vessel, to guard his offspring. Tvastr, his son being slain, offered Soma excluding Indra. Indra desired an invitation to the rite, but he did not invite him; (saying) 'Thou hast slain my son.' He made a disturbance of the sacrifice, and forcibly drank the Soma. The remains of it Tvastr cast upon the Ahavaniya (fire), (saying), 'Hail! wax great, Indra's foe.
