If you want to see the bottom of the water in a lake from above, the water has to be quite. If the water is turbulent, you can't. If the water has lots of objects, you can't. If the water has any color or turbidity, you can't. It has to be absolutely clear and quite in order to see the bottom best. Anything you do to this water, it will just add extra noise and turbulence. You can not make a turbulent water quite by doing something. Anything you do will go against your goal. You have to learn the technique of letting it just be and wait. Only then it can quite itself so that you can watch what it is.

With this background, now we have to find the best thing to experiment or examine in order to examine the reality. What is the best thing in the universe to examine. There are multitude of options. Atom, subatomic particles, energies, lights or other electromagnetic radiations, elements, molecules, planets, stars, galaxies, minerals, water, seas, plants, animals, man, mind and spirit. Among all of theses what has everything in it? The best candidate is us, the human. What is the most complicated physical structure know to exist in the universe? It's the human brain. What is the most powerful instrument known to exist in the universe? It's human thought and power of imagination. What is most accessible to us? It is again us, the human. Thus the best object in the known universe you can examine and assess is your own body and mind. It is you. Man is the famous allegorical "microcosm" of the "macrocosm" or the whole universe. If you know yourself and know how your body and mind operates and why does it operate the way it does, you will get closer to real mystery of existence. Hence the wise saying goes "Know Thyself". Given you have done your homework and had your thought honed and trained [see the "How valid is your thinking" essay], the universe will open up and reveal its mystery to you. This "you" is not a special you. Anybody who genuinely undertake the quest, will be that "you". In order to understand yourself better, you need to see your inside as clearly as possible. But there is always some noise inside our mind, our thoughts, likings, wantings, opinions, attachments, preference and intellect. All these creates turbulence and obstructing the view to know yourself better. You have to master the techniques to remove all those unoriginal, unnecessary foreign particles to remove turbidity and purify the water of your mind in order to see the beautiful bottom of the Ground.

I will introduce you into the vast universe inside you by giving an example of the source of a common desire. During the process of growing up, all it started from the very first kiss of your mother. You can not remember the kiss, affection and care from your mother during first 6 months of your life but your body and mind still remembers it, although it's not recollectable in your conscious memory. How can you know that your body and mind still has the memory of it? You can find the answer by asking why you want attention, care and support today from your significant others, without any apparent reason. You think you want care and love because you just want it? Think again.We learn things and then forget the learning episode, then that forgotten associative learning becomes our so called "pure" desire. We then believe our desire is genuinely pure, unconditional and not tied with anything. You just want something because you like it or you want it. Oh fool! It is not as simple as you might think. Think again. Think hard. Attention and approval is the prime addiction we have but we do not remember when we got addicted to this attention and approval seeking behavior in first place. Now you know! Although many of the things that we do or want is either because of biologic need or for utilitarian drive but do we do everything for these mundane reason or do we want those for something else? I am not going to give you the answer. You have to find it for yourself.
