जन्म कर्म च मे दिव्यमेवं यो वेत्ति तत्त्वतः।
त्यक्त्वा देहं पुनर्जन्म नैति मामेति सोऽर्जुन।।4.9।।
।।4.9।। हे अर्जुन मेरा जन्म और कर्म दिव्य है इस प्रकार जो पुरुष तत्त्वत जानता है वह शरीर को त्यागकर फिर जन्म को नहीं प्राप्त होता वह मुझे ही प्राप्त होता है।।
For the purpose of showing that moksa or complete liberation from the cycle of birth and death is only possible through complete knowledge of His essence and not by partial knowledge does Lord Krishna speak thus. The complete knowledge is by the knowledge of the Vedic scriptures. That is the way Lord Krishna must be adored. In the Kurma Purana it is stated that: who lives their life following the principles advised in the Vedic scriptures and adores Him accordingly, to those does the Supreme Lord reveal Himself and not to others. So it is clarified that only proceeding in this manner is salvation and liberation achieved and not by any other method digressing from the Vedic scriptures and this is irrevocable. The adjective tattvatah signifies that the entire scope of knowledge is essential. Regarding it thus this is not contradictory. In the Skanda Purana it has been stated that a human being will not be knowledgeable by understanding a single principle without first knowing the entirety of the principles and even Shiva is not capable of doing so, therefore one should diligently endeavour to be aware of all the principles. Now begins the summation. Only by learning and comprehending the knowledge revealed in the Vedic scriptures is moksa or liberation possible. By knowing and furthermore correlating this knowledge from different Vedic texts and applying it to ones everyday life will the ultimate attainment be gained and no other way. It should be clearly understood that the mere knowledge of the facts and details of the Supreme Lords appearance and divine pastimes will not enable one to attain liberation from the material existence without having first applied this learning through the medium of the Vedic scriptures fully into ones life and all that ones life encompasses.
