Came across this today in Your Soul’s Compass:

We’ve defined the Soul’s Compass as an intelligence located in the heart that’s capable of perceiving and responding to the good. In Hebrew there’s a concept called yetzer ha-tov – the urge to good. Sometimes yetzer -ha-tov is imagined sitting on one shoulder, and yetzer ha-ra’ – the evil urge – on the other. We grow in wisdom through our attempts to inquire into, and ultimately transcend the tension of those opposite impulses. The function of the evil urge is to clarify the good, the true, and the beautiful by motivating us to orient to the visible fruits of Spirit in our choices.

St. Ignatius of Loyola, the founder of the Jesuit order, was the Catholic dean of discernment. In the late 15th century, when he was born, discernment was indeed centered on distinguishing good from evil in the classical theological sense of whether a thought came from God or the devil. In the theology of Ignatius, which reflected the thinking of the time, the devil was thought to be a crafty creature intent on leading us astray who was separate from our own more primitive, instinctive desires and inclinations. But regardless of where the “evil urge” originates – most likely from our own inborn nature and conditioning – we can easily distinguish it from the action of our higher nature by the inner state it produces, which Ignatius described as desolation in contrast to consolation.

Consolation is a feeling of inner warmth, of being loved by and loving the Creator. A state of interior joy, consolation is characterized by a quiet mind and an open heart. One feels inspired, confident, courageous… held and supported by unseen but beneficent forces.

Desolation is a state of interior disturbance that Ignatius called “darkness of the soul.” Sadness, sloth, and separateness from God are its hallmarks. Today’s common maladies of burnout, depression, despondency, addiction and hopelessness are all symptoms of desolation.

This is fine example of how authors Joan Borysenko and Gordon Dveirin bring wisdom from the past and from differing traditions to their open-ended inquiry into spiritual guidance. Your Soul’s Compass is a great blend of insight from the past and present into the question – What is Spiritual Guidance?
