Srimad-Bhagavatam: Canto 1 - Chapter 1 - Verse 46
Sanskrit:
तद् धर्मज्ञ महाभाग भवद्भिर्गौरवं कुलम् ।वृजिनं नार्हति प्राप्तुं पूज्यं वन्द्यमभीक्ष्णश: ॥ ४६ ॥
ITRANS:
tad dharmajña mahā-bhāgabhavadbhir gauravaṁ kulamvṛjinaṁ nārhati prāptuṁpūjyaṁ vandyam abhīkṣṇaśaḥ
Translation:
O most fortunate one who know the principles of religion, it is not good for you to cause grief to glorious family members who are always respectable and worshipful.
Purport:
A slight insult for a respectable family is sufficient to invoke grief. Therefore, a cultured man should always be careful in dealing with worshipful family members.
