The seventh chapter of the Bhagavad Gita is Gyaan Vigyana Yoga . In this chapter, Krishna reveals that he is the Supreme Truth, the principal cause and the sustaining force of everything. He reveals his illusionary energy in this material world called Maya, which is very difficult to overcome but those who surrender their minds unto Him attain Him easily. He also describes the four types of people who surrender to Him in devotion and the four kinds that don't. Krishna confirms that He is the Ultimate Reality and those who realize this Truth reach the pinnacle of spiritual realization and unite with the Lord.
O Dhananjaya, there is nothing else whatsoever higher than Myself. All this is strung on Me like pearls on a string.
OPEN VERSEO son of Kunti, I am the taste of water, I am the effulgence of the moon and the sun; (the letter) Om in all the Vedas, the sound in space, and manhood in men.
OPEN VERSEI am also the sweet fragrance in the earth; I am the brilliance in the fire, and the life in all beings; and I am the austerity of the ascetics.
OPEN VERSEO Partha, know Me to be the eternal Seed of all beings. I am the intellect of the intelligent, I am the courage of the courageous.
OPEN VERSEAnd of the strong I am the strength which is devoid of passion and attachment. Among creatures I am desire which is not contrary to righteousness, O scion of the Bharata dynasty.
OPEN VERSEThose things that indeed are made of (the quality of) sattva, and those things that are made of (the quality of) rajas and tamas, know them to have sprung from Me alone. However, I am not in them; they are in Me!
OPEN VERSE
