Three questions. Follow the path.
How much time do I have?
Two hours or less: The Early Hours or a shortened Closed Door. Both compress to a single focused block. The Early Hours can work in 90 minutes if your morning is tight.
Three to four hours: Any liturgy works. This is the native length of most liturgies.
A full morning or afternoon: The Walkabout, the Silent Half-Day, or Iron Sharpens Iron. These liturgies need room to breathe.
Am I alone or with someone?
Alone: The Closed Door, The Early Hours, The Silent Half-Day, or The Sabbath Afternoon. These four are built for solitude.
With one other person: The Walkabout (a friend) or The Mentor Walk (a mentor/mentee pair). The Walkabout assumes a rough peer relationship. The Mentor Walk assumes a defined directional relationship.
With a small group of peers: Iron Sharpens Iron. Three is the right number. Two collapses into a mentoring dynamic. Four or more dilutes the speaking time enough to reduce honesty.
With a spouse or family: The Sabbath Afternoon. It is the only liturgy designed for that context.
What do I most need right now?
I am depleted and running empty: The Silent Half-Day or The Sabbath Afternoon. These are liturgies of receiving, not doing.
I am carrying something specific and need to process it: The Mentor Walk or Iron Sharpens Iron. One gives you a mentor who listens. The other gives you peers who pray.
I feel spiritually thin but functionally fine: The Early Hours or The Closed Door. These rebuild the interior life from the inside without requiring you to name a crisis.
I want renewal through creation and friendship: The Walkabout. It is the most joyful liturgy in the set.
I feel scattered and need to recollect: The Closed Door. Organization and prayer in the same block. The list is not the enemy of the spiritual; it is often the gate.
These seven liturgies are not exhaustive. They are starting points. The best micro retreat you ever take will probably be one you adapt or invent. The only requirement is that it be real: a genuine pause, not a productive pause dressed up in retreat language.
Begin with whichever liturgy you are most likely to actually schedule.
