Whenever we try to find the difference between requirement and pleasure, we get unstable line between these two. Because one can be another in any span of time, so before I start I want to describe a state when we become unconscious and how we react.
So we are the creation of nature and also a part of nature. We can feel certain type of forces around ourselves and lust can be one of those. It can be a requirement or just a way to pleasure but certainly it is. I was thinking about the difference. So, essential difference between pleasure and need is that need is a requirement, we require it or we are going to finish. Like, food is our requirement, air is our requirement, water is our requirement. But they are required only to live and for more there will be different requirements. Pleasure is a state when we do nothing and it can be called as super bliss. Like we are falling in a bottomless pit. When everything is gone also you feel yourself lost and the state to have nothing. There is nothing wrong in having the pleasure but it's wrong to have pleasure by sacrificing the things that are required. Instead of philosophy let's elaborate the reality and reality is, natural forces are there, our own force is also there, when we stop or oppose something we start becoming more stronger and this is also a law of nature. That grows from your essense and lead to storage of power. Some time storage is also destroyed when we try to oppose mighty force. So essentially it's not the question about right or wrong it's the question about having more or less awareness. Awareness always rises, it is the consciousness that vibrates. Our definitions of right and wring changes with the growth of awareness and it lasts till your end. More clearer picture starts coming there with more amount of it. Maturity is when you understand that particular either by experiencing it by self or by another one's experience. Level of maturity can never go to end but it always keeps the tendency to grow. What we negate in our selves is actually we are accepting it in another way. My friend Monu says, '' our mind thinks in pictures only and it has the words also in the pictures, hence when we are negating something, we are actually practicing it in our subconscious. Thought makes the way from the neurons of mind and it is ultimately the energy, which is magnetic in nature. Hence wherever it goes, it creates a magnetic field and that's the reason when we are unconscious we think of that thing. These are the fundamentals. Since Lust is not by birth it appears in school days and grows according to environment and the Institutes who think they have suppressed this feeling actually they are doing opposite. Because they are not just programming their desires but they are making the practice of this more deeper and ultimately it blasts a day. That's not the right way.
Laws of conservation of energy says that energy can neither be created nor be destroyed but it can be transformed from one form to another. But I don't say that transform the whole sexual energy in spirituality. Nature is utmost important and nature has made us to reproduce basically. Still if lust is overpowering your thought process and intelligence it's taking your human nature away. That's why it's important to learn the art of transformation. Now I can give you just the possibility that lust can be transformed to spiritual energy. But, how? I can't explain this time. Hope you will get the better perspective now. Till next be happy keep learning.
