Tamal Krishna: Thirteen and fourteen: "One should hold one's body, neck and head erect in a straight line and stare steadily at the tip of the nose. Thus, with an unagitated, subdued mind, devoid of fear, completely free from sex life, one should meditate upon Me within the heart and make Me the ultimate goal of life (BG 6.13)."
Prabhupāda: This is the process. First of all you have to select a nice place, solitary place and you have to execute alone. Not that you go to a yoga class and pay your fees and make some gymnastic and come back home and do all nonsense. You see? Don't be entrapped by all these ridiculous things, you see? Simply… Such society, I can declare, is the society of the cheaters and the cheated. You see? Here is the practice. Here you can see. And spoken by the supreme authority, Kṛṣṇa. Is there any person better yogi than Kṛṣṇa?
Here is the authoritative statement. That you have to practice like this. Now, one should hold one's body, first of all you have to select your place, holy place, alone, and special seat. Then you have to sit straight like this. "One should hold one's body, neck and head erect." Straight line. This is the yoga process. These things help to concentrate the mind. That's all. But the real purpose of yoga is to keep Kṛṣṇa always within yourself. Here it is said, stated, that "One should hold one's body, neck and head erect in a straight line and stare steadily at the tip of the nose." Now here, you have to see. And if you close, meditation, you'll sleep. I have seen. So many so-called meditators, they're sleeping. (makes snoring sound) I've seen it. You see? Because as soon as you close your eyes it is natural that you'll feel sleepy, you see? Therefore, half-closed. You have to see. That is the process. You have to see the tip of your nose, two eyes. Thus with unagitated mind. This process will help your mind to be fixed up, unagitated mind, subdued mind, devoid of fear. Yes. Because you have to, generally the yogis they used to practice in jungle and if he's thinking of, "Some tiger is coming or not, what is that?" (laughter) You see? Or some snake is coming. Because you have to sit down alone in a jungle. You see. There are so many animals. Tigers, and deers, and snake. So therefore it is specially stated, "devoid of fear." The skin of deer is specially used in yoga-āsana because it has got some medical effect that snakes do not come. If you sit down on that particular skin, the snakes and reptiles will not come there. That is the purpose. You'll not be disturbed. Devoid of fear, completely free from sex life. You see. If you indulge in sex life, you cannot fix up your mind in anything. That is the effect of brahmacārī life. If you remain brahmacārī without sex life, then you can be determined.
Just like we have seen a practical example of Mahatma Gandhi in India. Now, he started a movement, non-violent, non-cooperation. The movement, the fight was declared against the powerful British Empire, just see. And he determined that "I shall fight with the Britishers non-violent. Without any weapon." Because India was dependent, there was no weapon. And several times it was attempted, by armed revolution. But these Britishers are more powerful, they cut down. So Gandhi, he invented this method, that "I shall fight with the Britishers, even they become violent, I shall not become violent. So I shall get world sympathy." So this was his plan. He was great statesman. But his determination was so fixed up because he was a brahmacārī. From, at the age of thirty-six years he gave up. He had his wife but he gave up his sex life. He was a family man, he had children, he had his wife. But from the age of thirty-six, young man, a thirty-six year old, he gave up sex life with his wife. That made him so determined, that "I shall drive away these Britishers from the land of India," and he did it. You see? And actually he did it. So controlling the sex life, to refrain from sex life is so powerful. Even if you don't do anything, if you simply restrain your sex life, you become a very powerful man. People do not know the secret. So anything you do, if you want to do it with determination, you have to stop sex life. That is the secret.
So any process, take Vedic process. Either you take yoga process or bhakti process or jñāna process, in no process sex indulgence is allowed, no. Sex indulgence is only allowed, family life, just to beget very nice children. That's all. Sex life is not for sense enjoyment. Although there is enjoyment by nature. Unless there is enjoyment, why one should take responsibility of family life? That is the secret of nature's gift. But we should not take advantage of it. These are the secrets of life. (Aside): You can take it. These are the secrets of life. So yoga practice, such a nice thing. If you indulge in sex life, this is simply nonsense. Simply nonsense. And if anyone says that you go on with your sex life as much as you like, at the same time you become a yogi, simply pay my fees. I give you some ‘miracle mantra’. These are all nonsense. All nonsense. But we want to be cheated. We want to be cheated. We want something sublime very cheap. That means we want to be cheated. If you want very nice thing you must pay for it. "No. I shall go to a store, Sir, I can pay you ten cents, you give me the best thing for it." How can you expect for ten cent? If you want to purchase some valuable, if you want to purchase gold, then you have to pay for it. Similarly if you want perfection in yoga practice, then you have to pay for it like this. Don't make it childish affair. That is the instruction of Bhagavad-gītā. If you make it childish affair then you'll be cheated. And so many cheaters are ready to cheat you and take your money and go away. That's all. Here is the statement, authoritative statement. Free from sex life.
