Noble Silence. There is a reverential silence that can be felt by everyone in moments of sacredness, moments when the ego is forgotten. Keeping mauna is a way to open ourselves to this sacredness. According to the Bhagavad Gita, mauna is not about training our mouths, but about training our minds in not speaking. It is deeply transformative because it helps us quiet the mind and, more importantly, acknowledge the background of Stillness that is our Real Nature.
