Learn to self-conquest, persevere thus for a time, and you will perceive very clearly the advantage which you gain from it. As soon you apply yourself to orison, you will at once feel your senses gather themselves together: they seem like bees which return to the hive and there shut themselves up to work at the making of honey. At the first call of the will, they come back more and more quickly. At last, after countless exercises, of this kind, God disposes them to a state of utter rest and of perfect contemplation.
Teresa of AvilaHis Majesty knows best what is suitable for us. There's no need for us to be advising Him about what He should give us, for He can rightly tell us that we don't know what we're asking for (cf. Mt. 20:22). The whole aim of any person who is beginning prayer ? and don't forget this, because it's very important ? should be that he work and prepare himself with determination and every possible effort to bring his will into conformity with God's will.
