The gifts of the Holy Spirit which serve to contemplation are particularly those of understanding, wisdom, and science [knowledge], in regard to the intellect; and those of piety and fear, in regard to the will.

By the gift of wisdom we know the greatness of God and of heavenly things; and hence we are led to detach ourselves from all affection to creatures, in order to unite ourselves solely to God…
Louis Lallemant SJ (1578–1635)
