A human soul devoid of longing was a soul deformed, deprived of its highest good, sick unto death.

Souls will be unable to reach perfection who do not strive to be content with having nothing, in such fashion that their natural and spiritual desire is satisfied with emptiness; for this is necessary in order to reach the highest tranquility and peace of spirit. Hence the love of God in the pure and simple soul is almost continually in act.

The man who would prefer great wealth or strength more than love, more than friends, is diseased of soul.

The human soul has need of disciplined participation in a common task of public value, and it has need of personal initiative within this participation. The human soul has need of security and also of risk. The fear of violence or of hunger or of any other extreme evil is a sickness of the soul. The boredom produced by a complete absence of risk is also a sickness of the soul.
