The Geng stem activates four transformations in total: Hua Lu (化祿) on the star described here, plus Hua Quan on Wu Qu, Hua Ke on Tai Yin, Hua Ji on Tian Tong. Transformation into Prosperity amplifies the activated star’s capacity to generate, attract, or circulate value; here it lands on Tai Yang (太陽) (one of the 14 Main Stars).
Practitioner reading: Geng 化祿 on Tai Yang produces the chart-holder whose public-facing work generates income directly — teachers, broadcasters, politicians, sales leaders whose reputation translates into earnings. Particularly strong when the activated Tai Yang sits in a daylight palace.
At textbook level, the activation reads through wherever Tai Yang sits in the chart-holder’s 12 palaces (Self, Wealth, Career, Spouse, etc.). The activated star’s domain (warmth and natural visibility) tends to surface as the chart-holder’s most reliable source of beneficial circulation — opportunities, income, or favourable conditions in the activated star’s domain. The activation also re-fires during 10-year and annual luck cycles whenever the chart-holder’s temporary stem aligns with Geng, so the configuration described here is both natal and recurring.
Practitioners reading at depth weigh four further layers that this reference does not develop: which palace the activated Tai Yang occupies in the specific chart, what other stars share or oppose that palace, whether the chart-holder’s Hua Ji (化忌) activation interacts with this one, and how the current 10-year and annual luck cycles re-activate or deactivate the configuration. Synthesising these layers into a coherent prediction is the practitioner skill the Zi Wei Dou Shu Masterclass teaches.
