evam sva-bhaktayo rajan

 punar dvaravatim agat
 
Translation: 
 
O King, thus the Personality of Godhead, who is devoted to His own devotees, stayed for some time with His two great devotees Srutadeva and Bahulasva, teaching them the behavior of perfect saints. Then the Lord returned to Dvaraka.
 
Purport: 
 
In his narration of this pastime in Krsna, the Supreme Personality of Godhead, His Divine Grace A.C. Bhaktivedanta Swami Prabhupada concludes: “The instruction we receive from this incident is that King Bahulasva and Srutadeva the brahmana were accepted by the Lord on the same level because both were pure devotees. This is the real qualification for being recognized by the Supreme Personality of Godhead. Because it has become the fashion of this age to become falsely proud of having taken birth in the family of a ksatriya or a brahmana, we see persons without any qualification claiming to be brahmana or ksatriya or vaisya. But as it is stated in the scriptures, kalau sudra-sambhava: ‘In this Age of Kali, everyone is born a sudra.’ This is because there is no performance of the purificatory process known as samskaras, which begin from the time of the mother’s pregnancy and continue up to the point of the individual’s death. No one can be classified as a member of a particular caste, especially of a higher caste — brahmana, ksatriya or vaisya — simply by birthright. If one is not purified by the process of the seed-giving ceremony, or garbhadhana-samskara, he is immediately classified among the sudras because only the sudras do not undergo this purificatory process. Sex life without the purificatory process of Krsna consciousness is merely the seed-giving process of the sudras or the animals. But Krsna consciousness is the highest perfection, by which everyone can come to the platform of a Vaisnava. This includes having all the qualifications of a brahmana. The Vaisnavas are trained to become freed from the four kinds of sinful activities — illicit sex, indulgence in intoxicants, gambling and eating animal foodstuffs. No one can be on the brahminical platform without having these preliminary qualifications, and without becoming a qualified brahmana, one cannot become a pure devotee.”
 
Thus end the purports of the humble servants of His Divine Grace A.C. Bhaktivedanta Swami Prabhupada to the Tenth Canto, Eighty-sixth Chapter, of the Srimad-Bhagavatam, entitled “Arjuna Kidnaps Subhadra, and Krsna Blesses His Devotees.”
