What is Day Master balance?
Korean Saju reads useful strategy through a body-function logic: the Day Master is the chart's substance, while Yongsin is the functional application that best serves the chart. A Day Master can be weak, moderate, or strong; the Yongsin strategy changes accordingly. A weak Day Master needs support. A strong Day Master usually needs regulation, output, or controlled release. Charts with identical Yongsin elements can therefore follow different strategies depending on Day Master strength.
