तस्माच्छास्त्रं प्रमाणं ते कार्याकार्यव्यवस्थितौ।
ज्ञात्वा शास्त्रविधानोक्तं कर्म कर्तुमिहार्हसि।।16.24।।
16.24 Therefore, the scripture is your authority as regards the determination of what is to be done and what is not to be done. After understanding (your) duty as presented by scriptural injunction, you ought to perform (your duty) here.
16.24 Hence, the Sastra is to be the only authority for you in determining what should be done and what should not be done, viz., in deciding what ought to be accepted and what ought not be accepted. You should know, i.e., understand, neither more nor less than what constitutes the truth and the work enjoined in the injunctions of the Sastras which the Highest Reality called the Supreme Person revealed in the Vedas. The Vedic injunctions are supplemented by the Dharma-sastras, the Itihasas and the Puranas. The acts enjoined by them are the means for reaching Him and for pleasing Him. You should perform them; you should accept them alone.
