Spiritual Exercise

A regularly practiced discipline of the soul that leads to the transformation of one's inner state and the realization of philosophical virtue.

In the Stoic context, 'spiritual exercise' (Gk. askēsis, Lat. exercitatio) refers to a daily, repeated method of training the mind and willpower, through which the philosopher corrects their inner impressions and acts virtuously. It differs fundamentally from theoretical philosophy: whereas theory imparts knowledge, the exercise transforms the person themselves. Prosochē, meletē, and praemeditatio malorum are examples of such spiritual exercises, which remain ineffective without regular practice.
