If you apply your devotional service to Vāsudeva, vāsudeve bhagavati . . . Vāsudeva is the Supreme Personality of Godhead, bhagavati. Vāsudeve bhagavati bhakti-yogaḥ prayojitaḥ (SB 1.2.7). If you apply, if you engage yourself in devotional service to Vāsudeva, then the result will be janayaty āśu. Āśu means very soon, without delay; janayaty, generated. Janayaty āśu vairāgyam. Vairāgyam means knowledge by which one becomes detached from this material allurement. That is called vairāgya.
Simply by employing yourself in devotional service you get the highest knowledge. That is vairāgya. Without vairāgyam . . . jñānaṁ ca. Jñāna and vairāgya. Jñāna means knowledge, and vairāgya means detachment. This is required in this human form of life. As soon as you get the right knowledge that, "I am spirit soul. I am not anything of this material world. Somehow or other I have been in contact with this material world, and because I have desired to enjoy this material world in different capacities, therefore I am transmigrating from one type of body to another type, and I do not know since when this system began, but is still going on," this is called knowledge. To understand one's constitutional position and how he's suffering in this material world, that is called knowledge. Now that perfection of knowledge comes when one becomes vāsudeva-parāyaṇāḥ.
