Here in time we make holiday because the eternal birth which our loving God bore and bears unceasingly in eternity is now born in time, in human nature. St. Augustine says this birth is always happening. But if it happens not in me, what does it profit me? What matters is that it shall happen in me.
Consciousness individually and collectively shapes our material world. Our interior life constantly shapes our exterior life. This is why no matter how diverse our work in the external world, the "common work" of humanity —the only true way we can live our external lives — requires becoming conscious of the relationship between our inner and outer lives.
