Vegetarian diet

In the Mysticism tradition, vegetarian diets were seen as promoting purity and thus physical and spiritual purification or catharsis (κάθαρσις).

A vegetarian diet was seen as a form of asceticism or "askesis" (ἄσκησις), or a habit that becomes a specific way of life.

Of course, make sure you consult your physician before beginning any new diet routine to ensure that it is suitable for you.
