This verse is a reply to Arjuna's third question: What is the means of attaining to the transcendental position? As explained before, the material world is acting under the spell of the modes of material nature. One should not be disturbed by the activities of the modes of nature; instead of putting his consciousness into such activities, he may transfer his consciousness to Krsna activities. Krsna activities are known as bhakti-yoga-always acting for Krsna. This includes not only Krsna, but His different plenary expansions such as Rama and Narayana. He has innumerable expansions. One who is engaged in the service of any of the forms of Krsna, or of His plenary expansions, is considered to be transcendentally situated. One should also note that all the forms of Krsna are fully transcendental, blissful, full of knowledge and eternal. Such personalities of Godhead are omnipotent and omniscient, and they possess all transcendental qualities. So, if one engages himself in the service of Krsna or His plenary expansions with unfailing determination, although these modes of material nature are very difficult to overcome, he can overcome them easily. This is already explained in the Seventh Chapter. One who surrenders unto Krsna at once surmounts the influence of the modes of material nature. To be in Krsna consciousness or in devotional service means to acquire the equality of Krsna. The Lord says that His nature is eternal, blissful and full of knowledge, and the living entities are part and parcel of the Supreme, as gold particles are part of a gold mine. Thus the living entity's spiritual position is as good as gold, as good as Krsna in quality. The difference of individuality continues, otherwise there is no question of bhakti-yoga. Bhakti-yoga means that the Lord is there, the devotee is there and the activity of exchange of love between the Lord and the devotee is there. Therefore the individuality of two persons is present in the Supreme Personality of Godhead and the individual person, otherwise there is no meaning to bhakti-yoga. If one is not situated in the same transcendental position with the Lord, one cannot serve the Supreme Lord. To be a personal assistant to a king, one must acquire the qualifications. Thus the qualification is to become Brahman, or freed from all material contamination. It is said in the Vedic literature: brahmaiva san brahmapyeti. One can attain the Supreme Brahman by becoming Brahman. This means that one must qualitatively become one with Brahman. By attainment of Brahman, one does not lose his eternal Brahman identity as individual soul.
