Previously a concise description of what is to be known as constituting the ksetra or field of activity has been given by Lord Krishna beginning in verse six with maha-bhutani meaning the five fundamental elements of material nature and in verses 8 through 12 beginning with amanivitam or reverence the 20 excellent are enumerated as the means for acquiring the knowledge of atma-tattva or soul realisation up to perception of the eternal spiritual reality, knowing the Supreme Lord reside within the etheric heart of all living beings. Here Lord Krishna states mad bhakta meaning His devotees are knowledgeable of the reality regarding the ksetra, knowledgeable of the means by which to realise the atma or immortal soul which is of the nature of ksetra-jna or knower of the sphere of activity and distinctly different from the ksetra. Only His devotees are those situated in such knowledge and mad bhavayopapadyate meaning qualified to attain exclusive loving devotion to Him which is everlasting and eternal and which is different from samsara or the perpetual cycle of birth and death. Next Lord Krishna will explain the beginingless state of the two distinct natural verities of matter and soul conjoined together and the different functions each is engendered to perform as well as how these two verities came to be situated in this condition.
