I've used mudras with this quality or intention before. For me, Kurma Mudra seemed to be the most clearly in support of "resting in my inner sanctuary". I shared it in class today and some felt this similar pull toward inner quiet. "As we rest in the calm depths of our being, we experience inner silence and timelessness".
