पितृन् पूज्यादितः पश्चाद्देवतास्तर्पयन्ति वै । तस्मात् तान् सर्वयज्ञेन पुरुष: पूजयेत् सदा
pitṝn pūjyāditaḥ paścād devatās tarpayanti vai | tasmāt tān sarvayajñena puruṣaḥ pūjayet sadā ||
“智者先敬奉祖灵（Pitṛs），然后才以供献使诸神满足。因此，人应当恒常以一切祭祀与圣仪来礼敬祖灵。”

Educational Q&A
One should prioritize honoring the ancestors (Pitṛs) before worshipping the gods, and maintain continual reverence for the Pitṛs through all sacrificial and sacred rites—gratitude to lineage is presented as a primary dharmic obligation.
In Bhīṣma’s instruction on dharma (Anuśāsana Parva), he lays down a ritual-ethical order: first perform acts of honor and satisfaction for the ancestors, then proceed to offerings for the deities, concluding with an injunction to keep Pitṛ-worship as a constant practice.
