Regarding your question about thinking about sex, is that also one form of illicit sex or against our four principles? Yes, even thinking sex is the same as illicit sex, but one who is not advanced cannot avoid it. But that does not disturb our regular procedure. We should strongly follow all the regulations and principles and chant and these thoughts will come and go away. Thinking will come; even great saintly persons like Lord Siva are not free of thoughts that come, so what to speak of you. So we must say that such thinking is no offense because you are accustomed to this habit. But beyond thinking are feeling and willing, so even thoughts of sex connection may come, that is difficult even for saintly persons to avoid, still, in the further stages of feeling and willing we can easily conquer over this sex urge. Willing should be avoided and acting stopped, or else there is offense of breaking this basic prohibition of illicit sex-life. Because thinking comes I shall give it practical shape: that is nonsense, but because it is an old habit we are unable to check it unless we can understand the nature of feeling, willing and then action, and how by proper use of intelligence and prevent thoughts which must come from maturing into actions—that is the practical application of Krishna Consciousness regulative principles. Even Lord Caitanya Himself said that sometimes when I see a wooden form of a woman, my mind becomes agitated but that does not mean that we should give it practical shape, that is intelligence. One must be convinced that sex-life without exception means trouble, therefore he is able to stop it at the thinking stage by not allowing it to be felt, much less willed and acted. I am so much disgusted by this troublesome business of marriage, because nearly every day I receive some complaint from husband or wife, and practically this is not my business as sannyasi to be marriage counsellor, so henceforward I am not sanctioning any more marriages, and those who want to marry must know in advance and be prepared to make outside income to support wife and home separately from the temple, and in the temple husband and wife shall live separately, that must be or what is the meaning of spiritual society like ours? I made a concession, but how can I encourage something which has proven to be so much trouble?
Actually, the purpose of our life is to please Krishna; that is the business of the older children, to serve the father. So there is test for knowing if I am pleasing Krishna: If He reveals Himself to me, if I see Krishna, then I know I am pleasing Krishna. And another test is if my Spiritual Master is pleased by my service then I know that I am pleasing Krishna; it is very simple, because if I am following the prescribed regulative principles of my Spiritual Master, then without doubt I am pleasing him. So in this way, if you think it over, you will understand the answers to all your questions. Hope this meets you in good health.
