Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 17
Sanskrit:
गुरोर्नाधिगत: संज्ञां परीक्षन् भगवान् स्वराट् ।ध्यायन् धिया सुरैर्युक्त: शर्म नालभतात्मन: ॥ १७ ॥
ITRANS:
guror nādhigataḥ saṁjñāṁparīkṣan bhagavān svarāṭdhyāyan dhiyā surair yuktaḥśarma nālabhatātmanaḥ
Translation:
Although Indra searched vigorously with the assistance of the other demigods, he could not find Bṛhaspati. Then Indra thought, “Alas, my spiritual master has become dissatisfied with me, and now I have no means of achieving good fortune.” Although Indra was surrounded by demigods, he could not find peace of mind.
