"This kind of inebriation does not overthrow reason"

I came across this great quote from Augustine tonight:

“However, if this objective is unattainable so long as we are in the body and exiled from the Lord, let us at least taste how sweet the Lord is, for He has given us the Spirit as a pledge, in whom we may experience His sweetness. Let us also thirst for the fountain of life itself, wherein we shall be inebriated and refreshed by a sober excess, like the tree which was planted near the running waters, bringing forth fruit in due season, and whose leaves do not fall to the ground. For, the Holy Spirit says: ‘But the children of men shall put their trust under the covert of thy wings. They shall be inebriated with the plenty of thy house; and thou shalt make them drink of the torrents of thy pleasure. For with thee is the fountain of life.’ This kind of inebriation does not overthrow reason, but transports it to the regions above, making it forgetful of all things earthly – but only when we are able to say with all our heart: ‘As the dear panteth after the fountains of water, so my soul panteth for thee, O God..’”
