The fourth chapter of the Bhagavad Gita is Jnana Karma Sanyasa Yoga. In this chapter, Krishna glorifies the Karma Yoga and imparts the Transcendental Knowledge (the knowledge of the soul and the Ultimate Truth) to Arjuna. He reveals the reason behind his appearance in this material world. He reveals that even though he is eternal, he reincarnates time after time to re-establish dharma and peace on this Earth. His births and activities are eternal and are never contaminated by material flaws. Those persons who know and understand this Truth engage in his devotion with full faith and eventually attain Him. They do not have to take birth in this world again.
Thus, various kinds of sacrifices lie spread at the mouth of the Vedas. Know them all to be born of action. Knowing thus, you will become liberated.
OPEN VERSEO destroyer of enemies, Knowledge considered as a sacrifice is greater than sacrifices requiring materials. O son of Prtha, all actions in their totality culminate in Knowledge.
OPEN VERSEKnow that through prostration, inquiry and service. The wise ones who have realized the Truth will impart the Knowledge to you.
OPEN VERSEKnowing which, O Pandava (Arjuna), you will not come under delusion again in this way, and through which you will see all beings without exception in the Self and also in Me.
OPEN VERSEEven if you be the worst sinner among all sinners, still you will cross over all the wickedness with the raft of Knowledge alone.
OPEN VERSEO Arjuna, as a blazing fire reduces pieces of wood to ashes, similarly the fire of Knowledge reduces all actions to ashes.
