Why 108? Why not more, or less?
Across many traditions, religions and cultures, the number 108 represents wholeness, or spiritual completion. There are 108 beads on a mala, 108 beads on a rosary, 108 sounds in the Sanskrit alphabet, Hindu deities have 108 names, Stonehenge is 108 feet in diameter, the diameter of the sun is 108 times the diameter of the Earth, and there are 108 stitches on a baseball. The number 1 can be thought to represent the individual; the number 0 can represent the whole or the community; and 8 can represent infinity. Together they suggest that all things good and whole come in the complete package of 108.
And why Monkeys?
Buddha described the human mind as being filled with monkeys; capricious, fanciful, distracting and carrying on endlessly. A goal of mindfulness practices like yoga and meditation is to become intimately aware of our monkey mind. While we may never tame it, we can start by observing its habits — how it tugs us away from the present into the past or future, or how it deludes us into believing our thoughts are reality. This simple awareness, practiced with patience and non-judgment, can help bring us back to our true selves. So, a monkey swoops from our logo to remind us of (and bring humor and understanding to) this constant work of facing and embracing the monkey mind.
