The silence that enfolds something kept unsaid points to the unsayable. By being wrapped in silence, what is arcane (kept hidden) comes to participate in what is esoteric (by its nature inexpressible). The secret becomes a symbol of the mystery, participating in what it points to, by the way in which it points to it.
“In short, all that we watch, listen to, and participate in has the potential to be a path working on some level. However, what separates such randomness and potentially harmful psychic exchanges, is that cabalistic Pathworking is organized, progressive, and ultimately transpersonal oriented.” [via]
