Thomas à Kempis (15th century)
One of the most popular guides ever for Christian contemplative life, divided into four books of detailed spiritual instruction.

Many things there are, to know which profiteth little or nothing to the soul. And foolish out of measure is he who attendeth upon other things rather than those which serve to his soul’s health.
