The man who wishes to experience the rays of the eternal sun, which is Christ Himself, will be seeing; and will dwell on the mountains of the East, by concentrating all his faculties, and lifting up his heart to God, free, and indifferent to joy and pain and all the creatures. There shines Christ, the sun of righteousness, on the free and exalted heart, and this is what I mean by the mountains. Christ, the glorious sun and divine effulgence, shines through and fires by his internal coming, and by the power of His Spirit, the free heart and all the powers of the soul. This is the first work of the internal coming in the exercises of desire. Just as fire inflames things which are thrown into it, so Christ inflames the hearts offered to Him in freedom and exultation at His internal coming, and He says in this coming: "Go forth by the exercises appropriate to this life." ON UNITY OF HEART FROM this heat is born unity of heart, for we cannot obtain true unity, unless the Spirit of God lights His flame in our heart. For this fire makes one and like unto itself all that it can overtop and transform. Unity gives a man the feeling of being concentrated with all his faculties on one point. It gives internal peace and repose of heart. Unity of heart is a bond which draws and binds together the body and the soul, and all exterior and interior forces, in the unity of love. HOW THE VIRTUES PROCEED FROM UNITY FROM this unity of heart is born inwardness or the internal life, for none can have inwardness unless he is one and united in himself; fervour or inwardness is the introversion of a man into his own heart, to comprehend and experience the internal operation or speech of God. Inwardness is a sensible flame of love, which the Spirit of God lights and kindles in a man, and a man knows not whence it comes, nor what has happened to him. ON SENSIBLE LOVE FROM inwardness is born a sensible love which penetrates the heart of man and the highest faculties of the soul. This love and delight none can experience who has not inwardness. Sensible love is the desire and appetite for God as for an eternal good in which all is contained. Sensible love renounces all the creatures, not as needs but as pleasures. Interior love feels itself touched from above by the eternal love which it must practise eternally Interior love willingly renounces and despises everything, in order to obtain that which it loves. ON DEVOTION FROM this sensible love is born devotion to God and His glory. For none can have a hungry devotion in his heart, unless he possesses the sensible love of God. Devotion excites and stimulates a man internally and externally to the service of God. It makes the body and soul abound in glory and merit in the eyes of God and men. God exacts devotion in all that we do. It purges the body and soul from all that might hold us back; it shows us the true path to blessedness. ON GRATITUDE
