In case you do not know :

Meditation is a practice of mindfulness, or focusing the mind on a particular object, thought, or activity to train attention and awareness, and achieve a mentally clear and emotionally calm and stable state.

Meditation is practiced in numerous religious traditions. The earliest records of meditation (dhyana) are found in the Upanishads, and meditation plays an important role in Hinduism, Jainism and Buddhism.Since the 19th century, Asian meditative techniques have spread to other cultures where they have also found application in non-spiritual contexts, such as business and health.

Meditation may significantly reduce stress, anxiety, depression, and pain, and enhance peace, perception,self-concept, and well-being. Research is ongoing to better understand the effects of meditation on health (psychological, neurological, and cardiovascular) and other areas.
