Traditional Day Master reading
Ji: Cultivated soil that receives and nourishes
Ji is pictured as the soil of a field or garden, receptive to cultivation and able to hold what growing things need. As a Day Master image, it suggests patient involvement, practical care and development through steady attention. Its reading turns on conditions: warmth, moisture and room for growth make the surrounding chart part of the metaphor.
