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.
All this world, deluded as it is by these three things made of the gunas (qualities), does not know Me who am transcendental to these and undecaying.OPEN VERSE
Since this divine Maya of Mine which is constituted by the gunas is difficult to cross over, (therefore) those who take refuge in Me alone cross over this Maya.OPEN VERSE
The foolish evildoers, who are the most depraved among men, who are deprived of (their) wisdom by Maya, and who resort to demoniacal ways, do not take refuge in Me.OPEN VERSE
O Arjuna, foremost of the Bharata dynasty, four classes of people of virtuous deeds adore Me: the afflicted, the seeker of Knowledge, the seeker of wealth and the man of Knowledge.OPEN VERSE
Of them, the man of Knowledge, endowed with constant steadfastness and one-pointed devotion, excels. For I am very much dear to the man of Knowledge, and he too is dear to Me.OPEN VERSE
All of these, indeed, are noble, but the man of Knowledge is the very Self. (This is) My opinion. For, with a steadfast mind, he is set on the path leading to Me alone who am the super-excellent Goal.OPEN VERSE
