Quick Answer
Centering Prayer is Thomas Keating's modern revival of the Christian apophatic contemplative tradition. Drawn from the 14th-century Cloud of Unknowing and Keating's Open Mind, Open Heart (1986), the practice consents to silence with a sacred word as the bell rung whenever attention wanders. Sit with what is given.
Tradition and source
Tradition
Christian contemplative (Thomas Keating, OCSO)
Classical source
Rooted in the 14th-c. The Cloud of Unknowing and the apophatic tradition of Pseudo-Dionysius (5th to 6th c.) and Meister Eckhart (13th to 14th c.)
Modern source
Thomas Keating, Open Mind, Open Heart (1986); the Centering Prayer movement (Contemplative Outreach, 1980s onward)
What this practice does
Keating distilled this from the apophatic tradition for modern practitioners, the contemplative-Christian counterpart to Zen sitting. The Cloud of Unknowing (14th c.) is the textual precedent. The practice resembles transcendental meditation in form but differs in intention: this is the practice of consent, not mantra-repetition.
How to practice
The instructions below run 20 to 30 minutes. Read through all the steps before you begin. The practice is not the goal; you are.
Sit comfortably; close your eyes.
Choose a sacred word that signifies your consent to God's presence (Keating's instruction); for secular practitioners, choose any single word, "open," "home," "silence."
When you notice thoughts arising, return gently to the word.
The word is not a mantra to be repeated continuously; it is the bell you ring when you notice you have wandered.
Twenty minutes is the standard session length, twice daily in the Keating curriculum.

Crystal companion
In Crystal Cassandra's work, certain stones are the somatic companion to certain practices. The pairing is not magical; it is a steady weight in the palm that becomes part of the noticing.
Smoky Quartz
Smoky Quartz is the stone the modern Western canon names for grounding work during contemplative dryness, its dark translucent structure carries the symbolic resonance of staying with what is. Many practitioners hold it during long-form sitting through the Long Winter. The classical pairing makes it the natural cross-sell for chronic groundlessness work.
