Commentary

Concluding this Chapter Shree Krishna uses the word iti in this verse, which means “these”. This is to imply that, “Arjun here I have given you the gist of all the hidden knowledge of the Vedic scriptures. From the description of the nature of the world to the differentiation between matter and spirit. Finally, the realization of the Absolute Truth, about oneself and the Supreme Divine Personality, God. I assure you that, whoever espouses this knowledge will be truly enlightened. Their deeds and endeavors will be definitely fruitful and take them towards their ultimate goal, which is God-realization.”
