No, Father, I do not believe in a personal God. Well, there is no way to provide a rationale proof for God. Well, Mr. Campbell, it was nice speaking with you. Joe Campbell would laugh years later that he had pulled a theological jiu-jitsu maneuver on the Catholic professor since the Father had focused his query on a personal God. And such might be a defense of a clever mystic as many mystics dismiss the notion of a personal God.
Mysticism is the art of union with Reality.
The essential characteristic of it is the attainment of a personal conviction by an individual that the human spirit and the divine Spirit have met, have found each other, and are in mutual and reciprocal correspondence as spirit with Spirit. Equally valid definitions may range from those of St. John of the Cross to Zen Buddhism. All of which, together, can probably more easily confuse then clarify. Most such definitions tend to give an impression that the self is negated as in the definition by Evelyn Underwood. Yet, when looking at Jones's definition, one notices that there is not a negation of the individual but a rather an intercommunion with the divine Spirit or God.
