In yoga, the word, chanting, is almost always used with either of the Sanskrit terms mantra, japa or kirtan. Japa yoga incorporates chanting, or mantra repetition. Kirtan is a yoga practice of devotional chanting. It is believed that chanting a name of a deity helps one to stay in communion with them.
Chanting opens the heart; stills, focuses and calms the mind; and offers the benefits of a yoga class or meditation, without the struggle or the striving to concentrate. The most popular and most often chanted mantra in yoga is the supreme mantra and the primal syllable, Om (or Aum).
Chanting Sanskrit mantras is very effective for one's consciousness. It also stimulates the chakras, providing a calming, cleansing and energizing effect. Each Sanskrit letter is represented by a sound that is associated with a specific chakra in the body.
