Quaker silence is a deep, focused, listening, communal silence.  I find it to be incredibly grounding and connecting and life-giving.

Thomas Kelly wrote, "In the Quaker practice of group worship on the basis of silence come special times when an electric hush and solemnity and depth of power steals over the worshippers. A blanket of divine covering comes over the room, and a quickening Presence pervades us, breaking down some part of the special privacy and isolation of our individual lives and bonding our spirits within a super-individual Life and Power—an objective, dynamic Presence which enfolds us all, nourishes our souls, speaks glad, unutterable comfort within us, and quickens in us depths that had before been slumbering. The Burning Bush has been kindled in our midst, and we stand together on holy ground."
