There are as many techniques in meditation as they is sand grains in the desert. The most used techniques of meditation can be sorted and classified according to their techniques and aspirations. One category emphasizes attention on a selected object, a thought, an image, sound, etc…. A second category encourages a non-reactive monitoring of present experience such as perception, thought, feelings, etc…This is referred to as "mindfulness". The third technique is a little more exotic and deals with moving beyond or "transcending" activity. Whichever technique you prefer, meditate on a regular basis and seek a mind with inner harmony.
