What makes use desire something?
Desire is something your mind wants you to have. There are two kinds of desires, the desire dictated by your unconscious mind which is the ego, or desire dictated by you conscious mind which is your true self. The desire from the ego mostly on superficial things, like material stuffs, car, nice clothes, accessories or forbidden desires. Whereas the conscious desire is mostly spiritual or how to become a better person, like desire to help the needy, the desire to be kind and compassionate to others. The first step to control the desire is to know ourself. If I desire something like chocolate cake and I know it's bad for my health, then I need to consciously think the bad effect to my health. If I desire someone that I know it's forbidden, and I let my emotion takes over myself, then I am not ready to control my ego. The ego doesn't care if you will get in trouble. I chose not to live my life that way, so every desire I want, I consciously think very well. I will not let my unconscious mind runs my life. I want to be in-charge of my life. Therefore, consciousness is happiness.
Desires and aversions are based on stored impressions of past experience (karma). Say that you have eaten a certain food and enjoyed it. When someone mentions that food now, you may find yourself desiring it. The new stimulus triggers the stored impression, creating desire.
Meditate daily to release stored impressions, attain Enlightenment, and enjoy Permanent Bliss. Peace to you!
I, wonder if your question is "What makes us desire something?" If so;
I'd say it is the remembrance of a pleasantry or the anticipation of such.
I remember opening a bottle of what I thought was one beverage and it had a totally different taste. I spit it out (cautiously), I said, "ugg" and twisted up my nose.
Both my anticipated and my actual drinks were fine, both did taste all right. The only difference was in expectation.
A, terrific philosopher, in my mind, who's name I'm not recalling, once said, "We run from fear, towards happiness". Pain is bad, and pleasure is good.
I, do believe, that is why we like certain things and thoughts, in life and not others. Oh! I also believe we make choices on which to enjoy.
The two major sources of desire that I am aware of are the biological desires which we all pretty much share, and the learned, or conditioned desires that can be extremely different in us all.
There are different forms of desire. The first is that you experience something which stimulates you greatly or gives you a feeling which is very pleasurable. Perhaps you get a tremendous perception of beauty when on a hiking trip and see the sunrise over a beautiful snow capped mountain and you are swept away by its natural beauty.
Perhaps you hear a wonderful piece of music that touches you deeply or makes you feel a sense of beauty or meaning that is deep and you feel uplifted.
You may see something attractive which is owned by someone else, such as a incredible sports car or an amazingly spectacular home.
In all these cases it is part of a process as far as what makes you then desire it. First there is the simple perception of something, then contact and the stimulation or pleasure one feels from the contact. Then thought, recognizing that it the object or experience triggers in you a strongly pleasurable feeling comes in and thinks "This is wonderful. I want to experience that again, or i wish I could possess that house, or sports car, or be in a relationship with that extremely attractive person, or experience that high from communing with nature on that hiking trip etc.
There is sensory perception of the object or event, then contact with the pleasurable feeling it might bring. Then thought comes in an wants the repetition of the experience or to hold on to it and the mechanics of desire has begun.
There are some desires which start with one not really finding the thing or event that pleasurable but can be, through repetition cultivated and eventually one builds up a liking for something and even becomes addicted to the feeling one derives from it, such as smoking cigarettes or cigars, coffee as well as other sensory "pleasures" which can be addictive. If you smoke cigarettes for example or talk to someone who has, they will tell you the first time they used one, they did not care for it at all, however through repeated cultivation of the experience, it wasn't long before they formed a habit of using it to repeat the pleasure that they eventually derived from smoking etc. Eventually they feel uneasy when they are without it, may have withdrawals etc.
I hope this helps to answer your question.
