Never become too holy or too spiritual. Let the Spirit align itself within you. Become what humanity can be. Nothing more and nothing less. There is no such thing as spiritual development or Higher Self or Greater Self or Lower Self. There is nothing to find, nowhere to go, nothing to reach up to. There is, however, LIFE, human life capable of Being itself. And that is already present in every moment of every day ... By relaxing very deeply and allowing your body to reach a point of stillness, the delicate strings of your Self will be found dancing with the deep current of love that is the Earth. This love is the dance of the still point in the open moment ... your Self is love in action.
And, paraphrasing Max Picard in THE WORLD OF SILENCE:
"The mark of the Divine in God's good creation is preserved by the connection with the world of silence. For Silence is a primary, objective reality, which cannot be traced back to anything else ..." except Love itself. Or, as one of the saints exclaimed, "When the abyss of God's immensity encounters the abyss of our nothingness, God embraces our nothingness!" Abyss calls to abyss in the Silence. Each time we enter into the Silence, we open ourselves to the Beloved in a unique and vulnerable way ... we open the eyes and ears of our heart to the Heart of the universe.
