There are various kinds of many fires on the earth and in the universe. Some are normal physical fire, spontaneous forest fire or bush fire, volcanic fire. And some special fires are fire of hunger, fire of hatred, fire of revenge, fire of anger, fire of jealousy, fire of desire, fire of lustfulness or fire of libido and many more. And also the hell-fire is. Among all above fires, the most, vast disastrous fire is the fire of lustfulness or fire of libido. This fire of lustfulness or fire of libido can set fire to the earth and to the universe and everything on and in the earth and the universe and also burn them all fully within less than a second. This fire of lustfulness or fire of libido is much more disastrous than even the hell-fire. As an example, we consider an average, well-educated, intelligent, calm, young or middle-aged, married male or female having good family status, social status, professional status and every good other physical status and things and also two or three pretty children with well-balanced physical family life. If this male or female gets caught in this fire of libido that completely unnecessary, he or she must become really mad. Then he or she definitely forgets all of his or her education, intelligence, age, family status, social status, professional status and all other physical status and things, discipline and even his beloved wife or her beloved husband and even pretty innocent children too. All above could happen within a second incidentally and suddenly. Then he or she kicks all his or her education, intelligence, age, family status, social status, professional status and all other physical status and things, discipline and even to his beloved wife or to her beloved husband and even to pretty innocent children and the bright future of their family life and the bright future of his or her pretty innocent children and jumps into the fire of libido as like a grass-hopper jumps into the bright burning fire of a lamp. After that he or she is burnt in the fire of libido and in the fire of heart, fire of conscience and fire of spirit until his or her death although external appearances of all of his or her look good and smooth. After that he or she is really mad in mind until death although external appearances of all of his or her look good and smooth. And if the hell-fire is truthful, he or she is burnt even in the hell-fire after even his or her death. For a moment we think that the male or female escaped from that fire of libido for a while and opens his or her blind eyes of fire of libido and looks at what happened. This moment it externally indicates that fire of libido is extinguished, but he or she can never be able to escape from past-present-future pursuing fire of heart, fire of conscience and fire of spirit until death. And he or she can never be able to escape from the hell-fire even after death if the hell-fire is truthful. On the other hand, the actual nature of this fire of libido is like this. After burning in the fire of heart, fire of conscience and fire of spirit and after losing all his or her loved, beloved and owned things and after getting countless insults, troubles, obstacles, stresses and so on, although he or she escapes from the fire of libido for a moment, definitely he or she who once got caught in unnecessary fire of libido will jump again habitually into the fire of libido forgetting all his or her past if he or she senses heat of unnecessary fire of libido again. We have to highly consider of the above point. And also this female will have the fire of inside libido until her menopause. Sometimes may be beyond that. But it is not forever at all. And this male may have fire of inside libido until his death only if he is healthy. So, we have to think that how many times he or she will jump into unnecessary fire of libido throughout his or her life time. And we have to think that how many priceless, countless, valuable things he or she lost forever. And we have to think that how many painful things, distresses, afflictions, agonies, troubles, obstacles, insults and stresses and so on he or she got in results. And we have to think that how many times he or she was burnt in the fire of heart, fire of conscience and fire of spirit. And we have to think that how many times he or she may be burnt in the hell-fire if the hell-fire is truthful. And finally we have to think that what he or she got as the victory and whether he or she satisfied forever through the unnecessary fire of libido and what kind of satisfaction he or she got through the unnecessary fire of libido for his or her whole life-time. However we know one thing that the cause for all above every kind of things is getting caught in the unnecessary fire of libido. But……The basic major need of all living-beings is propagating of self-kind or reproduction. This need is more important and vital than all other needs of living-beings. Actually fire of libido has been originated and evolved for this basic and major need of living-beings. So….As the most intelligent and wisest being on the earth, the human-beings have to produce a proper way of using this fire of libido for the correct target. This way of using fire of libido must be within proper, strict and accurate limits and amounts. For the excess fire of libido we, human-beings must produce a best fire-extinguisher. What should this fire-extinguisher for unnecessary excess fire of libido be? That may be the shaped, controlled, tuned, aimed and unaffected and untainted flow of thinking or thoughts which was tamed in the heart of human-being by a pure mind.
