"Perfect love casts out fear." It is not be thinking ourselve sright that we cease to fear. It is simply by loving, and abandoning ourselves to the One whom we love without returning to self. That is what makes death sweet and precious. When we are dead to ourselves, the death of the body is only the consummation of the work of grace.
It is only in silence and through silence that we can interiorize what is beyond our comprehension and apprehend the power of a design larger than ourselves: it is the medium of transcendence.
