Nourishes.

Tradition, which is always old, is at the same time ever new because it is always reviving - born again in each new generation, to be lived and applied in a new and particular way. Convention is simply the ossification of social customs. The activities of conventional people are merely excuses for NOT acting in a more integrally human way. Tradition nourishes the life of the spirit; convention merely disguises its interior decay.

Thomas Merton
