Silence is a powerful practice to share with a group. This was recently reafirmed to me during a silent retreat that I led. I saw how the participants developed a harmonious group energy, silently supporting each other, as the retreat progressed. I remembered my own experience on similar retreats, feeling an unspoken bond with others much deeper than if we had been speaking.
To some extent, we can experience this in a group meditations, each of us silently disengaging from the mental stories and touching that ground of being that we all share.
