Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 35

Sanskrit:

ब्रह्मस्वं दुरनुज्ञातं भुक्तं हन्ति त्रिपूरुषम् ।प्रसह्य तु बलाद् भुक्तं दश पूर्वान् दशापरान् ॥ ३५ ॥

ITRANS:

brahma-svaṁ duranujñātaṁbhuktaṁ hanti tri-pūruṣamprasahya tu balād bhuktaṁdaśa pūrvān daśāparān

Translation:

If a person enjoys a brāhmaṇa’s property without receiving due permission, that property destroys three generations of his family. But if he takes it by force or gets the government or other outsiders to help him usurp it, then ten generations of his ancestors and ten generations of his descendants are all destroyed.

Purport:

According to Śrīla Śrīdhara Svāmī, tri-pūruṣa refers to oneself, one’s sons and one’s grandsons.
