Bhagavad Gita 2.40

नेहाभिक्रमनाशोऽस्ति प्रत्यवायो न विद्यते।स्वल्पमप्यस्य धर्मस्य त्रायते महतो भयात् ॥२.४०॥

nehābhikramanāśo’sti pratyavāyo na vidyatesvalpamapyasya dharmasya trāyate mahato bhayāt

In this, there is no loss of effort, nor is there any harm produced, nor any transgression. Even a little of this knowledge protects one from great fear.
