Let {the soul} try, without forcing itself or causing any turmoil, to put a stop to all discursive reasoning, yet not to suspend the understanding, nor to cease from all thought, though it is well for it to remember that is is in God's presence and Who this God is. If feeling this should lead it into a state of absorption, well and good; but it should not try to understand what this state is, because that is a gift bestowed upon the will. The will, then, should be left to enjoy it, and should not labour except for uttering a few loving words, for although in such a case one may not be striving to cease from thought, such cessation often comes, though for a very short time.

(Saint Teresa of Avila)
