Not all meditations may be very deep, but with regular practice the effects of meditation accumulate and become easier and deeper. The calm of meditation, along with stability and a clarity of focus, begins to carry over more and more into other daily activities. For some people, meditation may be a spiritual practice, but it is not a religion. Meditation can be part of the of practice of religion, as in Hinduism and Buddhism. There are many biblical references to meditation.
Churches usually have a meditative atmosphere.
Meditation lets us connect with something within us that is peaceful, calm and refreshing, and that has some special meaning. Anyone can benefit from it, no matter what their personal or religious beliefs. Meditation is not the same as relaxation. Meditation is relaxing and much more. The active process of meditation allows the body to relax and can offset the effects of mental and physical stress far more than passive relaxation.
