Verse 2.310

Sanskrit text and transliteration:

सत्यं हि श्रदिति प्राहुर्धत्ते धीः प्रत्यगात्मनि ।
तद्यतस्तां महात्मानः श्रद्धामित्यूचिरे धियम् ॥ ३१० ॥

satyaṃ hi śraditi prāhurdhatte dhīḥ pratyagātmani |
tadyatastāṃ mahātmānaḥ śraddhāmityūcire dhiyam || 310 ||

English translation of verse 2.310:

Truth, indeed, is what is meant by śrat. Since the intellect holds the truth in it, the wise speak of the intellect as faith. (Or, by śrat, Brahman is meant.) The intellect holds it in the inward Self.

Notes:

This verse explains the meaning of the word śraddhā. Śrat means truth, and dhā means to hold. Śrat may also mean Brahman which is implied by the word satya [satyam]. The intellect which is purified by the practice of śama, etc., can hold the truth or know the inward Self as Brahman. Hence the intellect is referred to by the word śraddhā.
