A mantra (Sanskrit: मन्त्र, romanized: mantra, English pronunciation /ˈmæntrə, ˈmɑːn-, ˈmʌn-/) is a sacred utterance, a numinous sound, a syllable, word or phonemes, or group of words in Sanskrit believed by practitioners to have religious, magical or spiritual powers in Hinduism. Some mantras have a syntactic structure and literal meaning, while others do not.
The earliest mantras were composed in Vedic Sanskrit in India, and are at least 3500 years old. Mantras now exist in various schools of Hinduism, Buddhism, Jainism, and Sikhism. In Japanese Shingon tradition, the word Shingon means mantra. Similar hymns, antiphons, chants, compositions, and concepts are found in Zoroastrianism, Taoism, Christianity, and elsewhere.
The use, structure, function, importance, and types of mantras vary according to the school and philosophy of Hinduism and Buddhism. Mantras serve a central role in tantra. In this school, mantras are considered to be a sacred formula and a deeply personal ritual, effective only after initiation. In other schools of Hinduism, Buddhism, Jainism or Sikhism, initiation is not a requirement.
Mantras come in many forms, including ṛc (verses from the Rigveda for example) and sāman (musical chants from the Sāmaveda for example). They are typically melodic, mathematically structured meters, believed to be resonant with numinous qualities. At its simplest, the word ॐ (Aum, Om) serves as a mantra, it is believed to be the first sound which was originated on earth. Aum sound when produced creates a reverberation in the body which helps the body and mind to be calm. In more sophisticated forms, mantras are melodic phrases with spiritual interpretations such as a human longing for truth, reality, light, immortality, peace, love, knowledge, and action. Some mantras without literal meaning are musically uplifting and spiritually meaningful.https://en.wikipedia.org/wiki/Mantra
