Meditation techniques can differ
Meditation can charge our mind. It's the action or activity in which we turn the direction of observation of our mind within ourselves. There are many techniques of meditation. The most popular one is breathing meditation. We observe our breathing in and out. If you go to the library or bookstore and look for a meditation guide book, most of the book will discuss this technique. Recently a technique called mindfulness has become more and more popular, especially in United States. In this technique we don't focus only on breathing, but to any movement. For example, for walking meditation, we will be mindful of the actions of each foot from left to right, when we raise it and when we let it down.
