The Bhagavad Gita is considered by eastern and western scholars alike to be among the greatest spiritual books the world has ever known. In a very clear and wonderful way the Supreme Lord Krishna describes the science of self-realization and the exact process by which a human being can establish their eternal relationship with God. In terms of pure, spiritual knowledge the Bhagavad Gita is incomparable. Its intrinsic beauty is that its knowledge applies to all human beings and does not postulate any sectarian ideology or secular view. It is approachable from the sanctified realms of all religions and is glorified as the epitome of all spiritual teachings. This is because proficiency in the Bhagavad Gita reveals the eternal principles which are fundamental and essential for spiritual life from all perspectives and allows one to perfectly understand the esoteric truths hidden within all religious scriptures. Many great thinkers from our times such as Albert Einstein, Mahatma Gandhi and Albert Schweizer as well as Madhvacarya, Sankara and Ramanuja from bygone ages have all contemplated and deliberated upon its timeless message. The primary purpose of the Bhagavad Gita is to illuminate for all of humanity the realization of the true nature of divinity; for the highest spiritual conception and the greatest material perfection is to attain love of God.

In the first six chapters of Bhagavad-gita the knower of the body, the living entity, and the position by which he can understand the Supreme Lord are described. Stress was given to devotional service: yoginam api sarvesam. "Of all yogis or transcendentalists, one who always thinks of Me within himself is best."

In the middle six chapters of the Bhagavad-gita, the Supreme Personality of Godhead and the relationship between the individual soul and the Supersoul in regard to devotional service are described. The superior position of the Supreme Personality of Godhead and the subordinate position of the individual soul are defined in these chapters. The living entities are subordinate under all circumstances, but in their forgetfulness, they are suffering. When enlightened by pious activities, they approach the Supreme Lord in different capacities as the distressed, those in want of money, the inquisitive, and those in search of knowledge. That is also described.

From the Seventh Chapter to the end of the Twelfth Chapter, Sri Krsna in detail reveals the Absolute truth, the Supreme Personality of Godhead. The words idam viditva indicate that one should try to understand the instructions given by Sri Krsna in this chapter and the Seventh Chapter of Bhagavad-gita. One should try to understand these chapters not by scholarship or mental speculation but by hearing them in association with devotees. Chapters Six through Twelve are the essence of the Bhagavad-gita. The first six and the last six chapters are like coverings for the middle six chapters, which are especially protected by the Lord. If one is fortunate enough to understand Bhagavad-gita---especially these middle six chapters in the association of devotees, then his life at once becomes glorified beyond all penances, sacrificies, charities, speculations, etc., for one can achieve all the results of these activities simply by Krsna consciousness.

Previously, beginning with the Seventh Chapter, the Lord has already explained His different energies and how they are acting. Now in this chapter (10) He explains His specific opulences to Arjuna. In the previous chapter He has clearly explained His different energies to establish devotion in firm conviction. Again in this chapter He tells Arjuna about His manifestations and various opulences.

Now, starting with the Thirteenth Chapter, how the living entity comes into contact with material nature and how he is delivered through the different methods of fruitive activities, cultivation of knowledge, and the discharge of devotional service are explained. Although the living entity is completely different from the material body, he somehow becomes related. This is also explained.

In the third six chapters, knowledge, renunciation, the activities of material nature, and devotional service were being described. It was concluded that all acts should be performed in conjunction with the Supreme Lord, represented by the words om tat sat, which indicate Visnu, the Supreme Person. The third part of Bhagavad-gita has shown that devotional service and nothing else, is the ultimate purpose of life. This has been established by citing past acaryas and the Brahma Sutra, the Vedanta Sutra. Certain impersonalists consider themselves to have a monopoly on the Vedanta Sutra, but actually the Vedanta Sutra is meant for understanding devotional service, for the Lord Himself is the composer of Vedanta Sutra and He is its knower. That is described in the Fifteenth Chapter. In every scripture, every Veda, devotional service is the objective. That is explained in the Bhagavad-gita
