In Hindu and Buddhist traditions, a Mantra is a sacred sound, syllable, or phrase that is repeated (chanted or silently meditated upon) to invoke spiritual energy, focus the mind, and facilitate transformation. "Om" is considered the primordial mantra — the sound of creation itself. In Vedic astrology, each planet has specific mantras (such as "Om Namah Shivaya" for the Moon or "Om Shukraya Namaha" for Venus) used as remedies.
