Hidden stems and their Ten Gods

A branch is more than its surface element. Xu 戌 hides Wu 戊, Xin 辛, Ding 丁; read against the Day Master Ren 壬 they give the Ten God relations below. Hidden stems are what element strength is actually judged on — counting only the four visible stems badly understates what the branches carry.

Where Ren Xu 壬戌 sits in a chart

The day pillar is the only one read from itself — every Ten God in the year, month and hour pillars is defined relative to the Day Master Ren 壬. Two people born in the same year and month with different day stems therefore have completely different charts. In Ren Xu 壬戌 the Day Master Ren 壬 is yang Water and sits on Xu 戌, which is Earth; the relation between them is branch controls the Day Master. This seat is classically read as the Day Master's immediate environment.
