These instructions given by Lord Kṛṣṇa while talking with His friend the learned brāhmaṇa are very good for the guidance of human society. A system of human civilization that does not promote varṇa and āśrama is nothing but a polished animal society. Indulgence in sex life by a man or woman living single is never acceptable in human society. A man should strictly follow the principles of brahmacārī life or, with the permission of the spiritual master, should get married. Single life with illicit sex is animal life, for the animals have no such institution as marriage.
Modern society does not aim at fulfilling the mission of human life, which is to go back home, back to Godhead. To fulfill this mission, the system of varṇa and āśrama must be followed. When the system is followed rigidly and consciously, it fulfills this mission, but when followed indirectly, without the guidance of superior authority, it simply creates a disturbing condition in human society, and there is no peace and prosperity.
Kṛṣṇa continued to talk with His brāhmaṇa friend: “My dear friend, I think you remember our activities during the days when we were living as students. You may remember that once we went to collect fuel from the forest on the order of the guru’s wife. While collecting the dried wood, we entered the dense forest and by chance became lost. There was an unexpected dust storm and then clouds and lightning in the sky and the explosive sound of thunder. Then sunset came, and we were lost in the dark jungle. After this, there was severe rainfall; the whole ground was overflooded with water, and we could not trace out the way to return to our guru’s āśrama. You may remember that heavy rainfall—it was not actually rainfall but a sort of devastation. On account of the dust storm and the heavy rain, we began to feel greatly pained, and in whichever direction we turned we were bewildered. In that distressed condition, we took each other’s hand and tried to find our way out. We passed the whole night in that way, and early in the morning, when our absence became known to our gurudeva, he sent his other disciples to search us out. He also came with them, and when they reached us in the jungle they found us very much distressed.
“With great compassion our gurudeva said, “My dear boys, it is very wonderful that you have suffered so much trouble for me. Everyone likes to take care of his body as the first consideration, but you are so good and faithful to your guru that without caring for bodily comforts you have taken so much trouble for me. I am glad to see that bona fide students like you will undergo any kind of trouble for the satisfaction of the spiritual master. That is the way for a bona fide disciple to become free from his debt to the spiritual master. It is the duty of the disciple to dedicate his life to the service of the spiritual master. My dear best of the twice-born, I am greatly pleased by your acts, and I bless you: May all your desires and ambitions be fulfilled. May the understanding of the Vedas which you have learned from me always continue to remain within your memory, so that at every moment you can remember the teachings of the Vedas and quote their instructions without difficulty. Thus you will never be disappointed in this life or the next.'
