Today was the feast of St. Teresa of Avila, Virgin and Doctor of the Church. From The Way of Perfection (Chapter 22):
O miserable world! Give hearty praise to God, daughters, that you have left so wretched a place, where people are honoured, not for their own selves, but for what they get from their tenants and vassals: if these fail them, they have no honour left. It is a curious thing, and when you go out to recreation together you should laugh about it, for it is a good way of spending your time to reflect how blindly people in the world spend theirs.
O Thou our Emperor! Supreme Power, Supreme Goodness, Wisdom Itself, without beginning, without end and without measure in Thy works: infinite are these and incomprehensible, a fathomless ocean of wonders, O Beauty containing within Thyself all beauties. O Very Strength! God help me! Would that I could command all the eloquence of mortals and all wisdom, so as to understand, as far as is possible here below, that to know nothing is everything, and thus to describe some of the many things on which we may meditate in order to learn something of the nature of this our Lord and Good.
When you approach God, then, try to think and realize Whom you are about to address and continue to do so while you are addressing Him. If we had a thousand lives, we should never fully understand how this Lord merits that we behave toward Him, before Whom even the angels tremble. He orders all things and He can do all things: with Him to will is to perform.
