Meditation

There are various types of meditation - prayer is probably the best known, but there is also TM (Transcendental Meditation), mindfulness meditation, and from the Eastern tradition, Zen meditation, Buddhist meditation, and Taoist meditation.
The meditation encompasses such diverse methods as:
Formal sitting in which the body is held immobile and the attention controlled. e.g., Zazen, Vipassana
Expressive practices, in which the body is let free and anything can happen. e.g., Siddha Yoga, the Latihan, the chaotic meditation of Rajneesh.
The practice of going about one's daily round of activities mindfully. e.g., Mahamudra, Shikan Taza, Gurdjieff's "self-remembering".
All these practices have one thing in common - they all focus on quietening the busy mind. The intention is not to remove stimulation but rather to direct your concentration to one healing element - one sound, one word, one image, or one's breath. When the mind is "filled" with the feeling of calm and peace, it cannot take off on its own and worry, stress out, or get depressed.

Namaste

I honor the place in you in which the entire universe dwells.
I honor the place in you which is of love, of truth, of light,
and of peace. When you are in that place in you,
and I am in that place in me,
We are One.
