'Jaaru', literally means, to slide. This is also called the Sarikal Adavu. In the RK Method, we refer to the standing series that end in Samapada as the Jaar Adavu series and the other sliding Adavus that use Muzhumandi, and Aalidam as Sarikal adavus for simplicity.
This Adavu incorporates the slide in different parts. Sometimes the slide is incorporated as the second leg slides toward the first and other times it is present as the extended foot drags in for the tap with both feet. This is the first variety that we practice in the Raadha Kalpa method, where the leg extends completely to Alidam as the second leg drags in. The variations occur in the incorporation of the slide as well as in the chosen torso movement.
