Here is the Sanskrit anuvad, Hindi anuvad, and English translation of Sankhya Yoga Chapter 2, Verse 2.40.
Sanskrit
नेहाभिक्रमनाशोऽस्ति प्रत्यवायो न विद्यते । स्वल्पमप्यस्य धर्मस्य त्रायते महतो भयात् ॥ २.४० ॥
Hindi
इस कर्मयोगमें आरम्भका अर्थात् बीजका नाश नहीं है और उलटा फलरूप दोष भी नहीं है, बल्कि इस कर्मयोगरूप धर्मका थोड़ा सा भी साधन जन्म मृत्युरूप महान् भयसे रक्षा कर लेता है|
English
When one practises Yoga, there is no fear of destruction; the person does not suffer a loss of honest effort in whatever he or she attempts. Even by practising a little bit of Yoga, one is protected from great fear ( of death or danger). Peace of mind is slowly obtained.
