varjayellavaṇaṃ sarvaṃ tathā jambūphalāni ca |
avakṣutāvaruditaṃ tathā śrāddheṣu varjayet || 41 ||

[paragraph continues] All kinds of salt should be excluded from the offerings made at Sraddhas, and also the fruits of the Eugenia Jamblana. All articles, again, upon which any one has spat or upon which tears have fallen should not be offered at Sraddhas. Among offerings made to the Pitris or with the Havya and Kavya offered to the deities, the potherb called Sudarsana (Menispermum tomentosum, Rox) should not be included. Havi mixed with this is not acceptable to Pitris. From the place where the Sraddha is being performed, the Chandala and the Swapacha should be excluded, as also all who wear clothes steeped in yellow, and persons affected with leprosy, or one who has been excasted (for transgressions), or one who is guilty of Brahmanicide, or a Brahmana of mixed descent or one who is the relative of an excasted man. These all should be excluded by persons possessed of wisdom from the place where a Sraddha is being performed,' Having said these words in days of old unto the Rishi Nimi of his own race, the illustrious Atri possessed of wealth of penances then went back to the Grandsire's assembly in Heaven.'"
