The word “mantra” is the combination of two Sanskrit words: “manas”, mind, and “tramati”, to free, to go through. Mantra is a sound which “goes through the mind” and reaches directly to the heart, the divine, the source of the being—that part in ourselves which already knows peace, quietness, and love. The vibration of our voice has powerful effects on the cells of our body-mind: it cleans them, it gives them a new order, a new harmony. Singing with other people reinforces this effect, and makes the experience of non-separation real, inside ourselves and with everything that surrounds us.
