The Supreme Lord Krishna considering Arjuna to be of a divine nature and a worthy recepient revealed the revelation of His aspect of Purusottama the absolute Supreme Being which is the confidential secret of all secrets. One who knows this shall become perpetually spiritually enlightened; acquiring all the attributes and wisdom by which one aspiring to attain Lord Krishna will possess. Such a one will have accomplished all works and duties and the result of every activity needed to attain Lord Krishna by renunciation and penance will in fact be acquired. This chapter which gives complete knowledge of the Supreme Lord Krishnas aspect of Purusottama that has been substantiated by the Vedic scriptures is alone sufficient to to accomplish what is stated in this verse. That this spiritual knowledge in itself is enough to manifest spiritual enlightenment and all that arises from it without having direct contact with the Supreme Being known as Purusottama as that is not a requirement for success. Chapter 15 has clearly delineated an explicit explanation of the three fundamentals of all existence which are Isvara the Supreme Lord, cit or sentient consciousness and achit or insentient matter which combined delivers a complete comprehensive solution to the meaning and mystery of existence throughout creation. This is the ontological thesis of Sri Ramanujas qualified monism philosophy of Visisthadvaita-veda which states that although all the energies of the Supreme Lord are one they each retain their individuality.
