Chapter 16, Verse 24
Part of 16: Daivāsura Sampad Vibhāg Yog — दैवासुरसम्पद्विभागयोगतस्माच्छास्त्रं प्रमाणं ते कार्याकार्यव्यवस्थितौ।ज्ञात्वा शास्त्रविधानोक्तं कर्म कर्तुमिहार्हसि॥
tasmāch chhāstraṁ pramāṇaṁ te kāryākārya-vyavasthitau jñātvā śhāstra-vidhānoktaṁ karma kartum ihārhasi
Therefore, let the scripture be thy authority in determining what ought to be done and what ought not to be done. Having known what is said in the ordinance of the scriptures, thou shouldst act in this world.
He who desires the welfare of the Self should not disregard the ?nds of the scriptures. A man who is anxious to obtain eternal bliss should respect the Vedas and the Smritis which lay down the code of right conduct. He should readily renounce whatever the scriptures teach him to abandon and accept whatever he is directed to accept. He who is thus entirely devoted to the Vedas cannot meet with misfortune, grief or delusion. No mother is more kind than the scriptures for they restrain us from doing evil and bestow on us the greatest good (liberation or Moksha). Therefore treat the scriptures with great respect. Renounce all that the scriptures prohibit. Whatever is worthy of being done, that thou shouldst do thoroughly with all thy heart and all thy strength. Thus in the Upanishads of the glorious Bhagavad Gita, the science of the Eternal, the scripture of Yoga, the dialogue between Sri Krishna and Arjuna, ends the sixteenth discourse entitledThe Yoga of the Division BetweenThe Divine and the Demoniacal. ,
