This Fifth Chapter is a practical explanation of Krsna consciousness, generally known as karma-yoga. The question of mental speculation as to how karma-yoga can give liberation is answered herewith. To work in Krsna consciousness is to work with the complete knowledge of the Lord as the predominator. Such work is not different from transcendental knowledge. Direct Krsna consciousness is bhakti-yoga, and jnana-yoga is a path leading to bhakti-yoga. Krsna consciousness means to work in full knowledge of one's relationship with the Supreme Absolute, and the perfection of this consciousness is full knowledge of Krsna, or the Supreme Personality of Godhead. A pure soul is the eternal servant of God as His fragmental part and parcel. He comes into contact with maya (illusion) due to the desire to lord it over maya, and that is the cause of his many sufferings. As long as he is in contact with matter, he has to execute work in terms of material necessities. Krsna consciousness, however, brings one into spiritual life even while one is within the jurisdiction of matter, for it is an arousing of spiritual existence by practice in the material world. The more one is advanced, the more he is freed from the clutches of matter. The Lord is not partial toward anyone. Everything depends on one's practical performance of duties in an effort to control the senses and conquer the influence of desire and anger. And, attaining Krsna consciousness by controlling the above-mentioned passions, one remains factually in the transcendental stage, or brahman-nirvana. The eightfold yoga mysticism is automatically practiced in Krsna consciousness because the ultimate purpose is served. There is gradual process of elevation in the practice of yama, niyama, asana, pratyahara, dhyana, dharana, pranayama, and samadhi. But these only preface perfection by devotional service, which alone can award peace to the human being. It is the highest perfection of life.
