Hari OM! In this chapter whatever has been previously stated about knowledge, the object of knowledge, prakriti or the material substratum pervading physical existence and the Purusa or the Supreme eternal consciousness is herein being categorically collated and elucidated by Lord Krishna. The means of developing spiritual intelligence through karma or activities was given by Lord Krishna in the first six chapters known as the Karma Yoga section and the means of achieving bhakti or exclusive loving devotion to Lord Krishna was revealed in the subsequent six chapters known as the Bhakti Yoga section along with the different manifestations of the Supreme Lord have all been arranged here together in summation. The jiva or embodied being is by itself eternal because it possesses an atma or eternal soul bestowed by the Lord Krishna which is an infinitesimal spark from Him; but the physical body although energized by the Supreme Lord is not eternal and disintegrates with time. Therefore the physical body is called sharira because it appears to die and since the Supreme Lord resides within all jivas as the atma He is known as ksetrajna or the consciousness within the ksetra or field of activity. This consciousness envelopes the physical body and is the source of the material senses which display their perceptions of duality in the ksetra of the physical body with emotions of like and dislike, happiness and misery, pleasant and unpleasant, love and hate etc. Now begins the summation. One who is freed from the modulations of desires and the bewilderment of attractions is able to unite with pure thoughts of spiritual consciousness. Such a jiva or embodied being is considered to have achieved moksa or liberation from material existence. The Narayana Scripture states that there are two manifestations of moksa. The superior form of moksa is known as suddha or pure liberation and its consciousness is always attuned and in harmony with dharma or eternal righteousness and the Supreme Lord Krishna or any of His authorized avatars or incarnations and expansions as revealed in Vedic scriptures. This consciousness has an all comprehensive knowledge about the atma or eternal soul and following the injunctions and ordinances of the Vedic scriptures is always engaged in performing different levels of bhakti or devotion to the Supreme Lord which eventually results in direct communion with the Supreme Lord eternal association with Him. The inferior form of moksa is known as asuric or demoniac liberation and its consciousness is antagonistic to dharma or eternal righteousness, it is addicted to perverse pleasures of the physical body, it has a distorted conceptions of the atma and is always desiring to perform degraded and prohibited activities. Its mentality is adverse to engaging in any service of the Supreme Lord and eventually without fail end up in the most fallen of species in the lowest hellish realms due to offenses made against the devotees of the Supreme Lord Krishna.
