Difference Between Concentration And Meditation

We are living in a dynamic world, where every particle is in constant flux. We cannot imagine a state where there is no action or movement. Even the apparent state of inaction reveals intense activity when analyzed scientifically. Still, there is an urge in man to be calm and silent without any activity, which induces him to go into the state of deep sleep every day.

 Meditation is an attempt to reach that state consciously, gradually reducing the number of thoughts and finally retaining only one thought in the mind.

Meditation is a special kind of concentration. In ordinary concentration, the mind is focused on one particular subject, and there can be many divergent thoughts related to that particular subject. Here the subject is one, but thoughts are many and dissimilar.
