Yoga studios across 35 countries will celebrate Global Mala Project later this month.
Thousands of yoga practioners from as far apart as Hong Kong, London and Sydney, will take part in 108 rounds of Sun Salutations, mantra, kriya or meditation from September 21 to 23.
Funds raised by the global event - which coincides with the Fall Equinox and UN International Peace Day - will go towards good causes, including Trees for The Future, War Child, YouthAids and Aids in Africa.
So far, Sting, Donna Karan and Christy Turlington have all pledged to turn their hand to veganism for the event.
Global Mala Project was set up by international yoga teacher Shiva Rea. The significance of the number 108 comes from the Mala - a sacred garland comprising 108 prayer beads and seen as a timeless tool for transformation through yoga.
