If you are familiar with the culture of the East, you have probably heard that the number 108 is considered sacred by the Dharmic Religions, such as Hinduism, Buddhism, and Jainism.
In Hinduism, for example, it is believed that the soul or inner self (Atman), goes through 108 stages of spiritual development.
Shaiva religions, particularly Lingayats, use malas (prayer beads) of 108 beads for prayer and meditation. I think, it is no coincidence...
