Meditation involves turning one’s attention to a single point. This can be done by focusing on the breath, on bodily sensations, or on a word or phrase, known as a mantra. In other words, meditation primarily takes your attention away from distracting thoughts and focusing preferably on the present moment.
Is it such a simple task, then why so many training sessions required?
The information in first para is like telling you how to drive a car. You understand it, but still you can not drive at an ab initio level. This itself requires some sessions of training. Then you requires more sessions and hours of practice to ‘drive as a driver’. Further more sessions and hours of driving will only let you get the benefit of an ‘enjoyable driving’.
Any task is so and therefore meditation too.
Meditation is more than other tasks. Why?
Meditation is a ‘health task’. The more proper it is done more the therapeutic benefits it will give. This can be achieved by doing meditation in more scientific and systematic manner, rather than in an amateur way.
