St. Teresa of Avila ...some words from The Interior Castle.

9. A soul which gives itself to prayer, either much or little, should on no account be kept within narrow bounds. Since God has given it such great dignity, permit it to wander at will through the
rooms of the castle, from the lowest to the highest. Let it not force itself to remain for very long in the same mansion, even that of self-knowledge. Mark well, however, that self-knowledge is
indispensable, even for those whom God takes to dwell in the same mansion with Himself. Nothing else, however elevated, perfects the soul which must never seek to forget its own nothingness. Let humility be always at work, like the bee at the honeycomb, or all will be lost. But, remember, the bee leaves its hive to fly in search of flowers and the soul should sometimes cease thinking of itself to rise in meditation on the grandeur and majesty of its God. It will learn its own baseness better thus than by self-contemplation, and will be freer from the reptiles which enter the first room where self-knowledge is acquired. Although it is a great grace from God to practise self-examination, yet ‘too much is as bad as too little,’ as they say; believe me, by God’s help, we shall advance more by contemplating the  Divinity than by keeping our eyes fixed on ourselves, poor creatures of earth that we are.
