Translation- Anyone who regularly engage in the battle of controlling the material senses on behalf of Lord Krsna, by engaging his senses in devotional service, easily achieve the perfection of material prosperity, mystic yogic powers, and transcendental knowledge of the Absolute Truth. Indeed, those perfections are resting in the palm of his hand.
My dear brother, I therefore request you to kindly understand the real meaning of the teachings of the Bhagavad-gita, and by this understanding you will achieve the causeless mercy of Lord Sri Krsna, the Supreme Personality of Godhead, and His Pure devotional service, which is the highest perfection of life.
The pure devotees of the Lord possess all good qualities. For them, having good qualities such as non-violence or freedom from anger is nothing at all.
Lord Krsna teaches the conditioned souls who thus take on the role that Arjuna did, and receive transcendental knowledge, which destroys their ignorance and suffering in the battlefield of life.
