In Jainism, the term "Charavalo" (चरवलो) refers to a specific type of shape used in sacred diagrams and yantras. Charavalo is described as a quadrilateral shape, often somewhat rectangular or trapezoidal, with slightly curved or uneven sides. It is not a regular geometric shape like a perfect square or rectangle but has a characteristic asymmetry.

Charavalo is used in the construction of various yantras and mandalas in Jain rituals and represents particular symbolic meanings in the Jain spiritual context.

If you need a precise description or depiction according to a specific text or tradition (Digambara or Shvetambara), please specify.
