Navel — inner transformative fire

The navel marks the transforming centre of the axis, where food, breath, and disciplined heat are visually gathered. This is an interpretive bridge between Siddha descriptions of bodily transformation and broader South Asian inner-heat imagery, not a clinical statement about metabolism or a treatment instruction.
