Happiness

Every beings in this world yearn for happiness. All beings will do all sorts of things to fulfill so that they can be happy, or rather they will do all possible things that they thought will lead to their happiness.
In the case of Buddhism, the Buddha puts it beautifully in three words: Gratification, Danger and Release, to describe happiness that we obtained or try to obtain through one of our sixth senses.
It's possible to reach the state of gratification, whatever things joy and happiness that we seek through our senses, and because of that beings continue seeking this happiness in order to "gratify" themselves. However, the Buddha warn that all these happiness have its danger. The danger is because whatever things it is, it is always have impermanence with it, meaning that it will not last forever although we are trying to so hard to protect so that we can always have that happiness in us all the time. And lastly, there is also release, in the sense that if we are able to let go from our attachment of that very gratification, then we will be able to be released from it.
These in a way are the essence of Buddhism ( or at least Early Buddhism), a religion (or whatever you call it), that put no meaning in prayer, ceremony, rituals, etc and focus on how teaching beings on what is the wisest way to achieve and obtain happiness, the highest possible happiness achievable from human beings.
(Note: Do note that unlike Early Buddhism, later form of Buddhism may deviate significantly from the early teachings. Some of them may become even closer to other religions than Early Buddhism - just to compare how close Tibetan Buddhism is closer in practice to Hinduism, and Catholicism in terms of its system. How close it is for Chinese Zen Buddhism to Taoism, etc).

As of most of beings in this world, I too have been trying to find various forms of happiness through one of sixth senses. The funny things of it is that when we do have that, the gratification tends to make me felt that these things will last forever and make me take things for granted that it will always be there. (Without remembering the "danger" that the Buddha advised us). And suddenly, when these things gone, disappear forever, then the mental suffering, lamentation, will be so overwhelming that sometimes I can't take it anymore.
One of the best examples in my life are probably three events that happened in my life two years ago. Every single things of the events (upon looking back), indeed remind me so much how much I have taken things for granted, thinking that those things will last forever. And indeed, when all these three disappeared from my life only in the space of one year, the me that left are the me that is feeling dejected. It seemed like someone that are being thrown to hell without knowing how to get out of it. It is like walking in the place of complete darkness, when I tried to walk further and further trying to find the light, no matter how much I tried to find, I can't seem to find it and I continue walking in darkness.
Those things are just the reflection of my state of my mind in the past of course. Thinking back, although the light is probably is not as bright yet, indeed in the end I have found some light. To put in the advice from the Buddha, it is simply that Release. When I am able to accept the fact that those things are impermanence, and will not last forever, and it is lost now, then somehow, magically it is not as painful anymore. Slowly, the wound is getting smaller and smaller and the light that I have been trying to find turn out to be just beside me all the time. It is just because I am so engulfed with darkness that I don't realize it. If I were to pause a while, and not focus on the darkness, probably I have realized it long time ago...
