योगवासिष्ठः yogavāsiṣṭhaḥ - book-6, chapter-69, verse-34

न जहाति मनः प्राणान्विना ज्ञानेन कर्हिचित् ।
तृणान्तरेणैव विना तृणाङ्गमिव तित्तिरिः ॥ ३४ ॥

na jahāti manaḥ prāṇānvinā jñānena karhicit ,
tṛṇāntareṇaiva vinā tṛṇāṅgamiva tittiriḥ 34

34. manaḥ jñānena vinā karhicit prāṇān na jahāti
tittiriḥ iva tṛṇa-antareṇa eva vinā tṛṇa-aṅgam

34. The mind (manas) never abandons the vital energies (prāṇa) without true knowledge (jñāna). It is exactly like a partridge (tittiri), which does not release one blade of grass (tṛṇāṅga) unless it can grasp another blade of grass (tṛṇāntara).
