The symbol for "Centerline"
Also, how I sign my name
"The hero is he who is immovably centered."
On a Columnar Self—How ample to relyIn Tumult—or Extremity—How good the CertaintyThat Lever cannot pry—And Wedge cannot divideConviction—That Granitic Base—Though None be on our Side—Suffice Us—for a Crowd—Ourself—and Rectitude—And that Assembly—not far offFrom furthest Spirit—God—

When we are in contact with the cosmic All and see the emergence of the crystals out of the manifestations of the crystal-mineral kingdom, we feel a sense of satisfaction. But very soon that state of anxiety and fear which I have already mentioned, returns again. Before discovering the divinely ordered world of crystals, we had been filled with fear. When we are aware of that divinely inspired world, this feeling of uncertainty vanishes; but after a time a strange sensation overtakes us and the fear returns, the feeling that the whole process of crystal formation is unsubstantial and provides only partial support.
Rudolf Steiner: "These lotus flowers must be present if a person wishes to have the capacity for transformation, for the latter involves these organs unfolding their petals away from the human self and encompassing the world of spirit, leaning into it. The transformational capacity we develop expresses itself for clairvoyant perception in the unfolding lotus flowers. The strengthened sense of I that one develops is an inner stability which we could call an elemental spine. We need to have both: lotus flowers, so that we can transform ourselves; and something resembling a spine in the physical world, an elemental spine, so that we can develop our strengthened I in the elemental world."
— John 3:30
Selah: The state of mind in prayer in which we relax from our affirmation of Truth and thanksgiving for good received and to be received, and "wait" on God in the stillness, that the Holy Spirit may reveal more of its inspirations to us and that it may establish our thoughts and our heart more firmly in the divine harmony and good.
Certain as I walk through life
Strength pours into my heart
Love in the core of my being
Hope in all I do
Trust in all my thinking
These six go with me through life
