Meditation is a practice in which an individual trains the mind or induces a mode of consciousness, either to realize some benefit or for the mind to simply acknowledge its content without becoming identified with that content, or as an end in itself. It has been practiced since antiquity as a component of numerous religious traditions and beliefs.
The term meditation refers to a broad variety of practices that includes techniques designed to promote relaxation, build internal energy or life force (qi, ki, prana, etc.) and develop compassion, love, patience, generosity and forgiveness. A particularly ambitious form of meditation aims at effortlessly sustained single-pointed concentration meant to enable its practitioner to enjoy an indestructible sense of well-being while engaging in any life activity.
The purpose of meditation is to make our mind calm and peaceful. If our mind is peaceful, we will be free from worries and mental discomfort, and so we will experience true happiness; but if our mind is not peaceful, we will find it very difficult to be happy, even if we are living in the very best conditions. If we train in meditation, our mind will gradually become more and more peaceful, and we will experience a purer and purer form of happiness. Eventually, we will be able to stay happy all the time, even in the most difficult circumstances.
