the purpose of askesis is to divest oneself of surplus weight, of spiritual fat… Askesis is not simply the practice of certain specific disciplines, it is an entire way of life, a lifestyle.
This passage provides the foundational definition of askesis in the Philokalic tradition: a comprehensive orientation of the whole person toward God rather than a set of discrete practices, aimed at stripping away spiritual excess.
