The manner by which such renunciation attains the Brahman or spiritual substratum pervading all existence is by pristine spiritual knowledge. Lord Krishna is requesting to hear and learn from Him how this can be accomplished.

How and by what means perfection is reached and the consciousness of the brahman or spiritual substratum pervading all existence is achieved is given in the next three verses. This perfection is the epitome of spiritual wisdom.

The perfection achieved by consistent performance of karma yoga or facilitating communion with the Supreme Lord by prescribed Vedic activities allows one to attain dhyana or meditation on Lord Krishna or any of His authorised incarnations and expansions as revealed in Vedic scriptures with bhakti or exclusive loving devotion. Lord Krishna is inviting one to learn how, in what manner and by what conduct one attains the the atma or immortal soul and the pure, consciousness of the brahman or spiritual substratum pervading all existence which are the two manifestations of the Supreme Lord who is the paramount of attainment and the goal of all endeavours.

Now Lord Krishna in order to clearly establish that the Supreme state of highest devotion is the eternal cause of internal communion with the Supreme Lord explains the process. The Supreme Lord specifically emphasises that only by exclusive loving devotion to the Supreme Lord is highest devotion of the Supreme state achieved. This is the paramount goal and ultimate attainment and it is eternally transcendent and infinite in nature. In the Bhagavat Purana, Canto 11, chapter 13, verse 14 beginning etavan yoga adisto is stated: The yoga system taught by Lord Krishna's devotees such as the Kumaras is withdrawing the mind from external objects and focusing it on the Supreme Lord. In the Visnu Purana the Prince Prahlad exclaims to the avatar or incarnation of Lord Krishna known as Narasinghadeva that: Just as the beloved has ardent love for the lover such is the depth of love that he wishes to have in his heart for the Supreme Lord.
