Prayer obtains what it is due to obtain — not what I personally want to obtain, which is different. It is useful that islands of prayer exist in the world, even if they are composed of only one person, or two, or three, or four.
How do we make a place sacred? By removing diversions. By creating silence. By bringing our presence and breath to a point of stillness. By listening with our skin, touching with our energy field, feeling with our senses. By holding intent as we enter a sacred place. By drawing out the power of a place with love, courage, and attention. By inviting spirit and welcoming it fully.
