Vedantasara - Verse 13
Sanskrit
एतेषां नित्यादीनां बुद्धिशुद्धिः परं प्रयोजनमुपासनानां तु चित्तैकाग्र्यं
तमेतमात्मानं वेदानुवचनेन ब्राह्मणा विविदिषन्ति यज्ञेन” (बृ उ ४.४.२२] इत्यादि श्रुतेःतपसा कल्मषं हन्ति” (मनु १२ - १०४] इत्यादि स्मृतेश्च
Swami Nikhilananda's Translation
Of these, Nitya and other works mainly serve the purpose of purifying the mind; but the Upasanas chiefly aim at the concentration of the mind, as in such Sruti passages, “Brahmanas seek to know this Self by the study of the Vedas, by sacrifice” (Brihadaranyaka-IV-4-22); as well as in such Smriti passages, “they destroy sins by practising austerities” (Manu 12.104)
