तस्माच्छास्त्रं प्रमाणं ते कार्याकार्यव्यवस्थितौ।
ज्ञात्वा शास्त्रविधानोक्तं कर्म कर्तुमिहार्हसि।।16.24।।
।।16.24।। इसलिए तुम्हारे लिए कर्तव्य और अकर्तव्य की व्यवस्था (निर्णय) में शास्त्र ही प्रमाण है शास्त्रोक्त विधान को जानकर तुम्हें अपने कर्म करने चाहिए।।
Sastra meaning the Vedic scriptures is the sole absolute supreme authority deciding all matters of existence guiding all creation as to what is to be done and what is not to be done. What the ordinances and injunctions of the Vedic scriptures enjoin along with their auxiliaries such as the Puranas, Upanisads, Itihasas, etc reveals that the highest truth is the Supreme Lord Krishna, that all activities should be engaged in as devotion and propitiation to Him and that this in itself constitutes the means of attaining Him. Realising these ultimate truths to be absolute reality, nothing more is required and one should sagaciously act with full faith in accordance therewith.
