Allow the Lord to work in us…

It is well to seek greater solitude so as to make room for the Lord and allow His Majesty to do His own work in us. The most we should do is occasionally, and quite gently, to utter a single word, like a person giving a little puff to a candle, when he sees it has almost gone out, so as to make it burn again; though, if it were fully alight, I suppose the only result of blowing it would be to put it out. I think the puff should be a gentle one because, if we begin to tax our brains by making up long speeches, the will may become active again.

— Saint Teresa of Avila (1515-1582)

Prayer and virtues…

Perseverance in prayer cleanses the intellect, illumines it, and fills it with the light of truth. The virtues, led by compassion, give the intellect peace and light. The cleansing of the intellect is not a dialectical, discursive and theoretical activity, but an act of grace through experience and is ethical in every respect. The intellect is purified by fasting, vigils, silence, prayer, and other ascetic practices.
–Saint Isaac of Syria (Seventh Century)

In God’s presence…

The following consideration should never be forgotten when we go to prayer, namely, that we draw near to God and place ourselves in His presence principally for two reasons. The first is to render to God the honor and the homage we owe Him, and this can be done without God speaking to us or we to Him, for the duty is fulfilled by acknowledging that He is our Creator. . . . The second reason is to speak to God and to listen to Him when He speaks to us by His inspirations and the interior movements of grace. One or other of these two advantages can never fail to be derived from prayer.
–Saint Francis de Sales (1567-1622)

Speak to our Lord…

If, then, we can speak to our Lord, let us do so in praise and supplication: if we are unable to speak, let us remain in his presence notwithstanding, offering him our silent homage; he will see us there, our patience will touch him and our silence will plead with him and win his favor. Another time, to our utter astonishment, he will take us by the hand, and converse with us, and make a hundred turns with us in his garden of prayer. And even should he never do this, still let us be content to know it is our duty to be in his retinue, and that it is a great favor and a greater honor for us that he suffers us in his presence.
–Saint Francis de Sales (1567-1622)
