Meditation is not an escape from reality. It is not a religious practice, however, it has been practiced in almost all of the world’s religions; including, Hinduism, Buddhism, Christianity, Judaism, and Islam. Meditation can be used to deepen your experience in religion, whichever one you so choose.
It is not a replacement for medical therapies. But, it can act as an adjunct to medical treatments.
Meditation is not about Mediums, Psychics or Sorcerers.
Meditation is a systematic skill that is practiced. A mind can never be truly turned off but can be put on idle.
It is merely an awareness of your own non-distracted mind.
