Ren and Gui Water through the seasons

先用庚金发水之源，次取丙火以除寒气。

专取辛金发源，次取丙火照暖。

— Qiong Tong Bao Jian, “Ren Water in the First Month” and “Gui Water in the First Month”

The book pictures Ren as rivers and Gui as rain or dew. These images introduce different emphases, but Ren does not always mean abundant Water and Gui does not always mean little Water. Season, roots, Metal support, Wood depletion, and Earth restraint determine the actual strength.

A source and a bank perform different tasks

Water has a source when Metal can generate it. It has a bank when suitable Earth can restrain it. Metal is Resource for Water; Earth is Authority. Weak Water under heavy Earth does not benefit from another bank. Strong Water with excessive Metal does not need endless additional Resource.

In early spring, vigorous Wood drains Water. The Ren passage prioritizes Geng as a source, while Gui prioritizes Xin. Both then consider Bing warmth. Metal generation and Fire warmth have separate tasks. Metal without roots or damaged by Fire cannot establish the source; rootless Bing suppressed by Water cannot establish warmth.

The Ren discussion also considers Wu restraining Water, but expressly does not apply it to every spring Ren. Without sufficient peer or Blade support, Wu need not be used. Xu Lewu explains the sequence: Water strengthened through peers and Resource may then need restraint. Compare Wood's depletion with incoming Metal and Water support.

For Gui, Bing and Xin can also bind each other. Their presence does not prove both functions remain available. Separation, or one visible and one hidden, requires examining whether generation and warmth survive. As spring cold recedes, the early-spring requirement for Bing cannot be copied unchanged.

Summer support must work together

Strong Si and Wu Fire can overwhelm Water through consumption and Earth pressure. The Ren chapters discuss peers and Resource helping each other: Water restrains Fire so Metal can survive, while Metal generates Water so it has a source. A small Metal presence under heavy Fire, or a rootless Water presence without supply, may fail to accomplish this.

The fourth month discusses Ren and Xin prominently; the fifth discusses Gui and Geng. Combinations such as Ding–Ren and Wu–Gui help explain the differences. Choose the actor that can retain its necessary function rather than being bound first. Summer Gui likewise requires assessing effective Metal–Water support and Fire–Earth pressure; the dew image does not establish permanent weakness.

Where substantial roots and Metal–Water support make Water strong, the emphasis changes again. Fire and Earth may then become useful Wealth and Authority. Actual support and complete formations explain the departure from the seasonal starting point.

Autumn Ren and Gui do not share one formula

Shen Metal supplies Water. For Ren in Shen, the book emphasizes rooted Wu as a bank, with Ding helping by restraining excessive Metal. Earth and Fire must be capable; a small Earth presence within a strong Water setting cannot be equated with substantial Earth rooted in Xu. Ding binding Ren also requires examining what restraint remains.

For Gui in Shen, Ding restraining excessive Metal Resource receives emphasis. In You, the book instead discusses Xin with Bing as support, describing warm Water and warm Metal. Both months are autumn, but their Metal quality, advancing cold, and chart needs differ. Neither “autumn Water likes Resource” nor “autumn Water must suppress Resource” covers both.

A period supporting useful Earth can favor defined responsibilities and stable undertakings for Ren. A period protecting necessary Fire in Gui's Metal–Water cooperation can favor accumulated capacity becoming results. The particular life area follows the working relationship.

Winter warmth must have support

Winter Ren often calls for Wu restraint and Bing support; deep-winter Gui gives Bing warmth greater urgency. Bing needs effective support through roots or Wood, while remaining protected from overwhelming Water. Wet or unsupported Wu still requires examination before it can be called a bank.

Ren in Zi begins with the monthly Yang Blade route; Gui in Zi begins with Establishing Prosperity, 建禄. Seasonal use of Bing or Wu does not make them the same pattern. Useful Fire and Earth periods can support development and firmer responsibilities. More Metal and Water damaging necessary Fire and Earth calls for preserving capacity and reducing unsupported commitments. Stable support for study, clear boundaries for responsibility, and explicit household divisions of work follow the source-and-bank relationships.
