At a high level, holiness has two parts, spiritual AND material.
The spiritual part is a ‘feeling’ of transcendence. Letting go and being one with all things, and ultimately with the source of all being.
The material part is virtue in action. Transcendence enables all the virtues and putting those virtues into action is the definition of love (love isn’t a a feeling, and it isn’t an action, it is ‘virtuous action’.)
So, holiness, is both a state (having the power) and a process (exercising the power). It is by both receiving and exercising this power consistently that one grows in holiness over time.
To grow in holiness, cultivate transcendence. But do not stop there, do something!
