The ninth chapter of the Bhagavad Gita is Raja Vidya Yoga. In this chapter, Krishna explains that He is Supreme and how this material existence is created, maintained and destroyed by His Yogmaya and all beings come and go under his supervision. He reveals the Role and the Importance of Bhakti (transcendental devotional service) towards our Spiritual Awakening. In such devotion, one must live for the God, offer everything that he possesses to Him and do everything for Him only. One who follows such devotion becomes free from the bonds of this material world and unites with the Lord.
O Arjuna, I give heat, I withhold and pour down rain. I am verily the nectar, and also death existence and nonexistence.OPEN VERSE
Those who are versed in the Vedas, who are drinkers of Soma and are purified of sin, pray for the heavenly goal by worshipping Me through sacrifices. Having reached the place (world) of the king of gods, which is the result of righteousness, they enjoy in heaven th divine pleasure of gods.OPEN VERSE
After having enjoyed that vast heavenly world, they enter into the human world on the exhaustion of their merit. Thus, those who follow the rites and duties prescribed in the three Vedas, and are desirous of pleasures, attain the state of going and returning.OPEN VERSE
Those persons who, becoming non-different from Me and meditative, worship Me everywhere, for them, who are ever attached (to Me), I arrange for securing what they lack and preserving what they have.OPEN VERSE
Even those who, being devoted to other deities and endowed with faith, worship (them), they also, O son of Kunti, worship Me alone (though) following the wrong method.OPEN VERSE
