Adhyāya 60: Dāna vs. Yajña—Royal Giving, Protection, and Karmic Share
यावन्ति रोमाणि भवन्ति धेन्वा- स्तावत् काल प्राप्प स गोप्रदानात् पुत्रांश्व पौत्रांश्ष कुलं च सर्व- मासप्तमं तारयते परत्र
vaiśampāyana uvāca | yāvanti romāṇi bhavanti dhenvāḥ tāvat kālaṁ prāpya sa gopradānāt | putrān ca pautrāṁś ca kulaṁ ca sarvam ā-saptamaṁ tārayate paratra ||
毗舍波耶那说：牛身上有多少根毛，施牛之人便因其果报享受天界之乐多少年。不仅如此：布施此牛之举，在彼世还能济度其子孙与全族，直至第七代。

Educational Q&A
The verse extols go-dāna (gifting a cow) as a highly meritorious act: its spiritual reward is vast (symbolized by the cow’s hairs as a measure of years in heaven) and it is portrayed as benefiting not only the donor but also the donor’s descendants up to seven generations, emphasizing dharma through generosity and responsibility toward one’s lineage.
In the Anuśāsana Parva’s instruction-focused discourse on gifts and dharma, Vaiśampāyana reports a teaching that quantifies and magnifies the फल (result) of cow-gifting: the donor enjoys heavenly pleasure for an immense duration, and the act is said to ‘carry across’ the donor’s family line in the hereafter up to the seventh generation.
