Prayer Wheels
Animated Mani Wheel

Tibetan Buddhists believe that saying the mantra (prayer) Om Mani Padme Hum, invites the blessings of Chenrezig, the embodiment of compassion.

HisHoliness, the Dalai Lama, has said that having the mantra on your computer works the same as a traditional Mani wheel. As the digital image spins around on your hard drive, it sends the peaceful prayer of compassion to all directions and purifies the area.

Animated images like this one are digital Mani wheels which can be placed on Web pages. Similar animated graphics can be used for Mani-wheel screen savers.

Rosary beads
Prayer beads are used to keep count of prayer repetitions or devotions and they are used in many religions. Catholics, and some Anglicans, use beads to pray the Rosary - a traditional set combination of prayers and meditations. Muslims, Buddhists, and Sikhs all use prayer beads as aids to counting.
