Doubt is a profound and effective spiritual motivation. Without doubt, no truism is transcended, no new knowledge found, no expansion of the imagination possible. Doubt is unsettling to the ego and those who are drawn to ideologies that promise the dispelling of doubt by preferring certainties never grow.

Fear of our own depths is the enemy.

What I refuse to face within myself will meet me in the exterior world through you, not as you are, but as I have so construed you.

In the second half of life, the questions become: 'Who, apart from the roles you play, are you? What does the soul ask of you?

There is some debate in professional circles about whether the so-called “midlife crisis” exists.

A neurosis is wherever we are allied against our true nature.

The truth about intimate relationships is that they can never be any better than our relationship with ourselves.

We serve the world by finding out what feeds us, and, having been fed, then share our gifts with others.

Anger is generally seen as an unwelcome presence in our midst, however natural it may be. Although each person, and each society, is charged with how anger is to be appropriately channeled, the denial of anger, or its continuous repression, is a deep source of our psychopathology and will invariably seek its expression in a less healthful fashion.

We are all meaning-seeking, meaning creating creatures and when we experience the loss of meaning, we suffer.
