Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 38-39
Sanskrit:
अहो एष महासारो धृतिमान् गिरिराडिव ।मौनेन साधयत्यर्थं बकवद् दृढनिश्चय: ॥ ३८ ॥इत्येके विहसन्त्येनमेके दुर्वातयन्ति च ।तं बबन्धुर्निरुरुधुर्यथा क्रीडनकं द्विजम् ॥ ३९ ॥
ITRANS:
aho eṣa mahā-sārodhṛtimān giri-rāḍ ivamaunena sādhayaty arthaṁbaka-vad dṛḍha-niścayaḥ
Translation:
Some would ridicule him by saying, “Just see this greatly powerful sage! He is as steadfast as the Himālaya Mountains. By practice of silence he strives for his goal with great determination, just like a heron.” Other persons would pass foul air upon him, and sometimes others would bind this twice-born brāhmaṇa in chains and keep him captive like a pet animal.
