All chaptersChapter 17: Sraddhatraya Vibhaga Yoga
Bhagavad Gita 17.15
Yoga through Discerning the Three Divisions of Faith
अनुद्वेगकरं वाक्यं सत्यं प्रियहितं च यत्। स्वाध्यायाभ्यसनं चैव वाङ्मयं तप उच्यते
anudvega-karaṁ vākyaṁ satyaṁ priya-hitaṁ cha yat svādhyāyābhyasanaṁ chaiva vāṅ-mayaṁ tapa uchyate
Speech that causes no excitement, is truthful, pleasant, and beneficial; the practice of studying the Vedas is called austerity of speech.
उद्वेग न करनेवाला, सत्य, प्रिय, हितकारक भाषण तथा स्वाध्याय और अभ्यास करना -- यह वाणी-सम्बन्धी तप कहा जाता है।
