毗湿摩说道：“在宗族亲眷之中，若有人于月相第十三日（trayodaśī，十三日）行施祖祭（śrāddha），便可成为族中最为卓越者；但若于第十四日（caturdaśī，十四日）行此祭，则其家中青年男子必定早夭。”

Educational Q&A
Bhishma teaches that the timing of śrāddha matters: performing it on trayodaśī is praised as elevating one’s standing among relatives, while performing it on caturdaśī is warned against due to harmful consequences for the household.
In the Anuśāsana Parva’s instruction on dharma, Bhishma advises Yudhiṣṭhira about proper observance of ancestral rites, specifically recommending trayodaśī for śrāddha and cautioning against inauspicious days.
