Shloka 22
अनुशासनपर्व अध्याय ९३ — तपस्, सदोपवास, विघसाशन, अतिथिप्रियता
Austerity, regulated fasting, residual-eating, and hospitality
तिलैरविरहितं श्राद्ध कृतं क्रोधवशेन च । यातुधाना: पिशाचाश्न विप्रलुम्पन्ति तद्धवि:
tilair avirahitaṁ śrāddhaṁ kṛtaṁ krodhavaśena ca | yātudhānāḥ piśācāś ca vipralumpanti tad dhaviḥ ||
毗湿摩说道：若施行施罗陀祭（śrāddha）而不置芝麻（tilā），或在嗔怒支配下行之，便不能达成其神圣本旨；其供献之物（havis）将被恶类所夺并玷污——夜图陀那（yātudhāna）与毗舍遮（piśāca）。此中教诫在于：奉祀祖先之礼，当具足应备之物，尤须心神澄定、恭敬虔肃，不可怀敌意与躁动而行。

Educational Q&A
Śrāddha should be performed with the prescribed elements (notably tila) and with inner composure. If done carelessly—especially in anger—the rite becomes vulnerable to obstruction and is considered fruitless, symbolically described as the offering being taken by yātudhānas and piśācas.
In the Anuśāsana Parva’s instruction on dharma, Bhīṣma teaches Yudhiṣṭhira the proper conduct of śrāddha. Here he warns that omissions (like lack of sesame) and a disturbed mental state (anger) undermine the rite, portrayed as malevolent beings spoiling the havis.
