OM MANI PADME HUM HRI
This mantra is known to purify the suffering caused knowingly or unknowingly. It is also perfect at times of illness and dying or when we are afraid.
The mantra is associated with clearing defilements from the six realms - Om for the God realm, Ma for the envious gods, Ni for the human realm, Pad for the animal realm, Me for the hungry ghosts and Hum for the hell realm.
The word mala means garland or rosary in Sanskrit. A mala consists of 108 or 27 beads. Buddha recommended the mantra practice as a path to enlightenment for ordinary people. Hold the mala gently, with respect. Start counting with the first bead after the 'guru' bead. Count a bead for each completed recitation. When you complete either 108 or 4x27 recitations, do not pass over the 'guru' bead. Instead, flip the mala around 180 degrees, and keep going the same direction. In closing you may like to dedicate merit to a specific person or group of people and all sentient beings.
