O unqualified, most heinous son of a brāhmaṇa, you have disobeyed my order and taken shelter of the party of my enemies. You have taught this poor boy about devotional service! What is this nonsense?
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
ब्रह्मबन्धो किमेतत्ते विपक्षं श्रयतासता । असारं ग्राहितो बालो मामनादृत्य दुर्मते
brahmabandho kimetatte vipakṣaṃ śrayatāsatā | asāraṃ grāhito bālo māmanādṛtya durmate
