In all cultures the meditation essence is the same and it is known that it can not succeed in imagery without constant application. It is useful to study by putting all your knowledges of meditation into a cave, because meditation is the only basis. In every spiritual doctrine, Buddhism, mysticism, Taoism, paganism, zen, these techniques do not change, they are common.
In fact, meditation is not the essence of meditation, which is based on imagery, which we call "meditation". These are imaginative exercises that can be applied after practicing basic meditation. Meditation is a word derived from the Latin word meditation, which means something to look at, to think over. So in essence what we call meditation is deeply thought-in fact, it does not "think mentally" - and in mystical terms it passes through this contemplation. So there is a deep thought that takes place without thinking. This can be a bit confusing, you can think of how we think without thinking. That's the point we should really touch.
First of all, in the meditation, mind is emptied and it is necessary to learn to empty the mind. When you empty your mind, you will have a deep sense of wisdom and awareness. This is exactly where you come into contact with this very deep subject, a flow from your soul to your consciousness, an enlightenment, an awareness flows, and you will gain an awareness-awakening and a clear vision of life. Thoughts of deliberation are not "philosophical questioning". Here the mind is purified. So long as we accept the glass as the mind, clean the dirty window and follow the truth behind the clear glass. When the glass is dirty, that is, when thousands of thoughts are in our minds, we can not see the truth, when the glass is cleaned, then we can gaze beyond the glass. This is the process of touching the truth beyond the mind, at which point you are not merely "intervening" or "judging" but only "observer" or spiritual self.
Believe it, it is much easier than the philosophy of practice ... You can read thousands of books about meditation, you can not grasp what you are before you do meditation. The words to explain this method are incompetent ...
