The more we know about the ultimate cause, the better we can understand the effects.
Raja-Vidya: The King of Knowledge is a collection of transcribed lectures by Srila Prabhupada on the ninth chapter of the Bhagavad-gita.
In that section of the Gita, Krishna tells Arjuna why He’s revealing divine knowledge to him; because Arjuna is free from envy. Srila Prabhupada points out that we can also understand the Bhagavad-gita to the degree we don’t resent God’s greatness. By knowing God as the source of everything, we can know everything else we need to know; we’re spirit and not matter. Loving God is the ultimate goal of life. If we think we’re everything, we’ll envy God, and the Bhagavad-gita won’t make sense to us.
The King of Knowledge suggests practical ways to enhance our self-knowledge and understanding of the Supreme Person. The result of such knowledge is freedom from the anxieties of this temporary, ever-changing world.
