The word Jivasara is a portmandeau, or one word created out of two words. In this case, Jivasara is made from the two major influence on Marni Task's yoga journey, Jivamukti Yoga founded by David Life and Sharon Gannon, and Anusara Yoga created by John Friend. It is not a merging of these to yoga styles, but rather both have heavily influenced and inspired Marni's own take on Yoga.
