mantra

In Hinduism and Buddhism, mantras are short syllables or phrases that are thought to have power. Mantras may be chanted by devotees as part of daily practice, or pronounced during rituals to invoke the deity’s power. In tantric Hinduism and Vajrayana Buddhism, practitioners perform meditative deity-yoga by first visualizing “root” or “seed” syllables, and then generating the yidam deities out of these mantras during the process known as visualization.
