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.
At the end of many births the man of Knowledge attains Me, (realizing) that Vasudeva is all. Such a high-souled one is very rare.OPEN VERSE

Whichever form (of a deity) any devotee wants to worship with faith, that very firm faith of his I strengthen.OPEN VERSE
Being imbued with that faith, that person engages in worshipping that form, and he gets those very desired results therefrom as they are dispensed by Me alone.OPEN VERSE
That result of theirs who are of poor intellect is indeed limited. The worshippers of gods go to the gods. My devotees go to Me alone.OPEN VERSE
