245:1 5, 1. Nârâyana (comp. the Âsvalâyana-Grihya-Parisishta III, 7) understands this Sûtra in a different way. 'After the tenth Tithi of the dark fortnight, on a Tithi with an odd number, is e. on the eleventh, thirteenth, or fifteenth.' The single Nakshatras are those the name of which does not denote two Nakshatras (as, for instance, the two Ashâdhâs). Comp. Kâty.-Sraut. XXV, 8, 1; Manu V, 59.
245:2 Urns, with or without protuberances like female breasts, are considered as female or male accordingly.
245:3 See chap. 2, 2.
245:4 Comp. chap. 2, 10.
246:7 Nârâyana explains pavana by sûrpa. He says that the 'performer' (kartri) repeats this and the following texts.
246:10 They should give a Srâddha to the deceased exclusively, according to the Ekoddishta rite.' Nârâyana.
