Sun Salutations by themselves are considered a sacred yogic practice - and an almost perfect set of movements to provide a full body "workout".  When repeated 108 times in a row, you will refresh yourself and connect your spirit with the magical number of 108, linked to growth of earthly living entities and with universal cosmic properties that can't be coincidental. The Sun's diameter is 108 times the distance to the earth. The earth's diameter is 108 times the distance to the moon. Growth cycles in a nautilus spiral are always represented as a ratio of 1.08 when comparing the distance of the edges of a nautilus shell from each other from the inner spiral. Numerous examples of the occurrence of 108 in earthly living entities affect the growth patterns of everything from sunflowers to the horns of a sheep. Taking advantage this naturally occurring organic earthly event during the equinox and solstice boosts our own strength, creates greater awareness of the world around us, and leads to growth on a physical and mental plane.
