"But when the yogi engages himself with sincere endeavor in making further progress, being washed of all contaminations, then ultimately, after many, many births of practice, he attains the supreme goal." (Bg. 6.45) When one is finally freed from all contaminations, he attains the supreme perfection of the yoga system—Krsna consciousness. Absorption in Krsna is the perfect stage, as Krsna Himself confirms:

bahunam janmanam ante
jnanavan mam prapadyate
vasudevah sarvam iti
sa mahatma sudurlabhah

"After many births and deaths, he who is actually in knowledge surrenders unto Me, knowing Me to be the cause of all causes and all that is. Such a great soul is very rare." (Bg. 7.19) Thus after many lifetimes of executing pious activities, when one becomes freed from all contaminations arising from illusory dualities, he engages in the transcendental service of the Lord. Sri Krsna concludes His discourse on this subject in this way:

yoginam api sarvesam
mad-gatenantaratmana
sraddhavan bhajate yo mam
sa me yuktatamo matah

"And of all yogis, he who always abides in Me with great faith, worshiping Me in transcendental loving service, is most intimately united with Me in yoga and is the highest of all." (Bg. 6.47)

It therefore follows that the culmination of all yogas lies in bhakti-yoga, the rendering of devotional service unto Krsna. Actually, all of the yogas delineated in Bhagavad-gita end on this note, for Krsna is the ultimate destination of all the yoga systems. from the beginning of karma-yoga to the end of bhakti-yoga is a long way to self-realization. Karma-yoga, without fruitive results, is the beginning of this path. When karma-yoga increases in knowledge and renunciation, the stage is called jnana-yoga, or the yoga of knowledge. When jnana-yoga increases in meditation on the Supersoul by different physical processes, and the mind is on Him, it is called astanga-yoga. And, when one surpasses astanga-yoga and comes to worship the Supreme Personality of Godhead, Krsna, that is called bhakti-yoga, the culmination. factually, bhakti-yoga is the ultimate goal, but to analyze bhakti-yoga minutely one has to understand the other processes. The yogi who is progressive is therefore on the true path to eternal good fortune. One who sticks to a particular point and does not make further progress is called by that particular name—karma-yogi, jnana-yogi, dhyana-yogi, raja-yogi, hatha-yogi, etc.—but if one is fortunate enough to come to the point of bhakti-yoga, Krsna consciousness, it is to be understood that he has surpassed all the other yoga systems.
