When the surface of a lake is still, one can see to the bottom very clearly.

This is impossible when the surface is agitated by waves.
In the same way, when the mind is still, with no thoughts or desires, you can see the "Self"

We can control the mental agitation by two means: by concentrating the mind either externally or internally.
Internally, we focus on the "Self" or the consciousness of "I am".
Externally, we focus on anything other than the "Self" or "I am".

When we take up some recreation on putting the ball into the hole (golf), the other thoughts are slowed down or stilled. We feel we have played a good game when we have achieved perfect concentration. The happiness we experience comes, not because the ball being put in the hole eighteen times, but because we have achieved perfect concentration eighteen times.

At that time, all the worries and problems of the world disappeared.
The mental ability to concentrate is inherent to all.
It is not extraordinary or mysterious.

Meditation is not something that a Yogi has to teach you;
You already have the ability to shut out thoughts.

The only difference between this and meditation (the positive way), is that generally we have learned to focus the mind externally on objects. When the mind is fully concentrated, time passes unnoticed, as if it did not exist. When the mind is focused, there is no time! Time is nothing but a modification of the mind.

The happiness achieved through the mind is temporary and fleeting;
it is limited by nature.

To achieve that state of lasting happiness and absolute peace, we must first know how to calm the mind, to concentrate and go beyond the mind. By turning the mind's concentration inward, upon the self, we can deepen that experience of perfect concentration.
This is the state of Meditation

Introduction to the techniques of Meditation

Meditation is an experience that cannot be described,
just as colours cannot be described to a blind man.
All ordinary experience is limited by Time, Space and Causation.
Our normal awareness and understanding do not transcend these bounds.

Finite experience, which is measured in terms of past, present and future, cannot be transcendental. Concepts of time are illusory, for they have no permanence. The present, immeasurably small and fleeting, cannot be grasped.

Past and future are non-existent in the present. We live in illusion.

The meditative state transcends all such limitations. In it there is neither past nor future, but only the consciousness of "I am" in the eternal NOW. It is only possible when all mental modifications are stilled.

The closest analogous state that we can experience is deep sleep, in which there is neither time, nor space, nor causation. Meditation, however, differs from deep sleep, for it works profound changes in the psyche. By curbing and stilling the oscillations of the mind, meditation brings mental peace.
On the physical level, meditation helps to prolong the body's anabolic process of growth and repair, and to reduce the catabolic or decaying process.
Ordinarily the anabolic process predominates until the age of 18. From 18 to 35 there is balance between the two, and after 35 the catabolic process dominates. Meditation can significantly reduce the catabolic decline. This is because of the innate receptivity of the body cells.

Each of our body cells is governed by the instinctive subconscious mind. They have both an individual and a collective consciousness. When the thoughts and desires pour into the body, the cells are activated; the body always obeys the group demand. It has been scientifically proven that positive thoughts bring positive result to cells.

As meditation brings about a prolonged positive state of mind, it rejuvenates body cells and retards decay.

Meditation teachings are widely available in Thailand for Thais and visitors alike, ranging from English language day classes in Bangkok through to intensive month-long Vipassana courses at remote retreats in the provinces ; More infos HERE
