What This Is
A short window in which the self enters its own storehouse. Each element has its 墓库, its grave-storehouse of gathered, stilled energy: Water (壬癸) in the 辰 hour, Wood (甲乙) in the 未 hour, Fire (丙丁) in the 戌 hour, Metal (庚辛) in the 丑 hour, Earth (戊己) in the 辰 or 戌 hour. When the hourly branch is the grave of the day master's element, the self's energy enters the grave for that two-hour interval. It is the finest-scale version of the burial — the self banked and quieted, briefly, within a single 时辰.
The register is withdrawal rather than harm: the chart's force drawn in for a window, then released as the hour passes.
When It Fires
It fires when the hourly branch equals the 墓库 of the day master's element — a daily occurrence, the same two-hour window each day. As with the daily burial, its character inverts if the grave is opened: when the decade or year carries a 刑 or 冲 against that storehouse, the buried energy releases instead of resting.
What It Changes
It quiets the window. For those two hours the day master's energy is in the grave, and the interval carries low force — better suited to rest and stillness than to action. 三命通会 names it for the selection of hours: when the hour enters the grave, it is better to rest still and not suited for movement. Effort pressed into such a window tends not to complete; the self is gathered in, not reaching out.
If the larger cycles open the grave, the same window reverses — the stored energy surfaces, and the interval becomes one well suited to decision, to resolving doubt, to a moment of inward clarity.
How To Read It
Read it by whether the grave is sealed or opened, and remember the scale. Sealed, it is simply a low-energy window — the classical 择时 reads it as an unfavorable interval for launching anything that needs full force, a time to hold rather than act. Opened by 刑冲 from the decade or year, the same window becomes favorable for decision-making, for resolving a hanging question, for introspection — the banked energy briefly available.
Because the hour is the finest resolution, the effect is modest and brief either way; it matters most as a tool for choosing when within a day to act or to wait. Never flat — stillness when sealed, a small opening when broken, and always weighed at the scale of a two-hour window.
Where This Shows Up
A window of this kind is felt as a natural lull — a couple of hours where energy dips, focus turns inward, and pushing hard feels against the grain. It is a fitting interval to rest, to let something settle, to step back from anything demanding full force. Traditional hour-selection avoids it for launches and commitments for exactly this reason.
When the grave is opened by the larger cycles, the same lull can carry an unexpected clarity — a short window where a decision crystallizes or a doubt resolves, the gathered self briefly surfacing. The texture is the storehouse at its smallest scale: a brief gathering-in, quiet when sealed and quietly clarifying when opened.
