Buddhists do not pray to a Creator God, but have meditation practices that resemble prayer. There is no fixed time for meditation or prayer but regular meditation, which can be several times a week or daily. During meditation, or prayer, Buddhists may recite or chant certain words and sounds, called mantras, repeatedly. These meditations may be done in front of an image of the Buddha (sometimes appearing as praying to the Buddha). Forms of meditation/prayer vary depending on the Buddhist denomination/tradition concerned.
