In Bhāgavata you will see that Ṛṣabhadeva says that "One should not become the spiritual master, one should not become the father, one should not become the mother, one should not become the husband—who cannot give relief from these miseries of material existence". It is the husband's duty also. Because the wife is under the protection of the husband, he has got so much responsibility.
Woman class and children class, they are taken in the same category. They require protection. They require protection. That is the Manu-saṁhitā. Na striyaṁ svatantratām arhati. Women should be under the protection. They should be given all protection. So the system of taking... Just like the Hindu system is... Just like a girl. Before attaining the age of puberty, she is handed over to a suitable boy to take charge before she gets youthful energy.
So this is the system of varṇāśrama-dharma. This is the system. The whole idea is that everyone should be given the chance of being liberated in this very life. No more waiting for again for further, another life. Who knows that I am going to be human being again? It may be by freaks of nature I become a cat, a dog, a cow, an animal.
Now we are very much enthusiastic to become good nationals. Suppose I am American, a very good national. Now, after death, suppose that if I become a cow. Then even I am national of this country, oh, I am destined to be sent to the slaughterhouse. You see? So we should not take the risk of next birth. In this life, in this birth, we should make a permanent solution of all miseries. That is Kṛṣṇa consciousness. Let us become Kṛṣṇa conscious in this very life and make a solution.
Now, this cātur-varṇyam, this plan of cātur-varṇyam, Lord says... You should always remember that this material creation, whole material creation... There are unlimited number of universes and, I mean to say, planets in each universe. In the Brahma-saṁhitā it is stated, yasya prabhā prabhavato jagad-aṇḍa-koṭi. Jagad-aṇḍa-koṭi (Bs. 5.40). Jagad-aṇḍa means this universe, and koṭi means hundred millions. Hundred millions. Not exactly one hundred millions, but numberless.
