Meditation and yoga are two sides of a same coin. Meditation is defined as the art of doing nothing at all. When you meditate you do not question your thoughts or try to control your emotions. You only focus your attention on breathing in and breathing out.
Practicing meditation helps you to become self-aware. It also helps to become aware of your surroundings. There are different meditational practices and serve different purposes. But there's one thing in common in between them i.e. they all help you to live a healthy life.
When you practice meditation, all your worries, sorrows and tension flies away as if there were none in the first place. Practicing yoga can help you make physically fit and flexible.
So it is important that you practice meditation and yoga every day.
