In order to solve the problem of sex, the minds first understand that both alternatives are equally creation of imagination working under influence of craving.
Foremost, you should try to get rid of lust, as all other vices are on account of it. For instance, if a parrot's throat is cut, it dies. But if its wings are clipped, it does not die, after some time the feathers of the wings grow back. Lust can be compared to the parrot's head. Therefore, when lust is still present and we conquer other evils, such as anger, the evils again revive; everything rises out of the head. But if lust is killed once and for all, every other evil is also destroyed; you have cut off its head.
There is no need to stop thoughts from coming. This is a very important thing. In no book it is mentioned. It is only for My lovers that I am pointing out today the secret of this spiritual darkness.
Lusty, good or bad thoughts should not be checked. Let them come, rather encourage them to come! Do not feel nervous or get despondent, but never allow them to express themselves in actions.
What happens then? To clean the slate of the mind these sanskaras should be spent in any way. If they are not spent in this birth they will have to be spent in the next birth. So they should be spent through thoughts only. If they are spent through physical actions, as we have said, new sanskaras are created. So they should only be spent mentally. When their force is spent, you are free.
Now why do these thoughts come? From where do they come? They are not borrowed, nor do they come from somewhere outside. They were deep within you. If they do not surface now, they will surge up some other time. So I repeat, don't worry, and if you follow Me hundred percent you will be free
Lust is gravest vice. Its sanskaras are of deepest red colour which are very difficult to wipe out. If lust is left it brings back other vices such as anger etc.
