Commentary

To conclude 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 this 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 endeavours will be definitely fruitful and take them towards their ultimate goal, which is God-realization.”
