In the seventh chapter, Shri Krishna taught that Vasudeva, the Supreme Brahman, is the object of worship. He taught His principalship in relation to all entities, animate and inanimate. His causality in relation to the entire universe; His being the support of all; His being denoted by all words as He has all entities for His body or modes; His controllership of all; His supremacy over all on account of His multitude of auspicious attributes; His being concealed by Sattva, Rajas and Tamas in the form of bodies and senses and as the objects of experience arising from the stream of evil Karma coming down from beginningless time, and of the removal of this obscuration by resorting to the Lord through virtuous deeds. He also taught the gradation among the worshippers arising from differences in the fruits aspired for by them and produced by the relative proportions of good acts performed for wealth, for knowledge of the true nature of the individual self, and for the attainment of the Lord. He taught the greatness of the aspirant who attains the Lord on account of his being dear to the Supreme Person, and for his being ever attached to the Lord through single-minded devotion. He referred to the rarity of such a devotee. Shri Krishna also mentioned the differences among the things that should be known and those that should be practised by the three classes of devotees. Now, in the eighth chapter Shri Krishna gives a detailed description of certain principles and practices that have already been treated in brief earlier.
