As the sun grows in power with the passing seasons, so the soul now experiences a steady increase in the power and splendour of the Divine Light, as it ascends in the heavens of consciousness and pours its heat and radiance into all the faculties of man. The in-beating of this energy and light brings the self into the tempestuous heats of high summer, or full illumination—the ‘fury of love,’ most fertile and dangerous epoch of the spiritual year. Thence, obedient to those laws of movement, that ‘double rhythm of renunciation and love’ which Kabir detected at the heart of the universal melody, it enters on a negative period of psychic fatigue and spiritual destitution; the ‘dark night of the soul.’ The sun descends in the heavens, the ardours of love grow cold. When this stage is fully established, says Ruysbroeck, the ‘September of the soul’ is come; the harvest and vintage—raw material of the life-giving Eucharist—is ripe. The flowering-time of spiritual joy and beauty is as nothing in its value for life compared with this still autumnal period of true fecundity, in which man is at last ‘affirmed’ in the spiritual life. This, then, is the curve of the self’s growth. Side by side with it runs the other curve of deliberate training: the education by which our wandering attention, our diffused undisciplined consciousness, is sharpened and focussed upon Reality. This training is needed by intellect and feeling; but most of all by the _will_, which Ruysbroeck, like the great English mystics, regards as the gathering-point of personality, the ‘spiritual heart.’ On every page of his writings the reference to that which the spiritual Light and Love do for man, is balanced by an insistence on that which man himself must do: the choices to be made, the ‘exercises’ to be performed, the tension and effort which must characterise the mystic way until its last phase is reached. Morally, these exercises consist in progressive renunciations on the one hand and acceptances on the other ‘for Love’s sake’; intellectually, in introversion, that turning inwards and concentration of consciousness, the stripping off of all images and emptying of the mind, which is the psychological method whereby human consciousness transcends the conditioned universe to which it has become adapted, and enters the contemplative world. Man’s attention to life is to change its character as he ascends the ladder of being. Therefore the old attachments must be cut before the new attachments can be formed. This is, of course, a commonplace of asceticism; and much of Ruysbroeck’s teaching on detachment, self-naughting and contemplation, is indeed simply the standard doctrine of Christian asceticism seen through a temperament.
