Meditation (dhyana) is the practice of turning your attention to a single point of reference. It can involve focusing on the breath, on bodily sensations, or on a word or phrase known in Sanskrit as a Mantra. Meditation is not a part of any religion; it is a science, which means that the process follows a particular order, has definite principles, and produces results that can be verified.
The belief that meditation is the art of silencing the mind, often leads to a sense of failure and consequently abandoning the practice. It is true that a feeling of calm and a quieter mind is sometimes a result, but the purpose of meditation is not to calm the mind or yourself. Simply observe the mind to see what is happening within. It is the nature of the mind to keep generating thoughts, endlessly. Our mind spins stories about our work, family, finances, health, etc., and has the tendency to get stuck in conditioned patterns of thinking, returning again and again to thoughts of anxiety, depression and limitation.
