The Adornment of the Spiritual Marriage, by Jan van Ruysbroeck, , at sacred-texts.com
A brief parable I will give to those who dwell in the tumult of love, that they may endure this state nobly and becomingly, and may attain to higher virtues. There is a small insect called the ant. It is strong and sagacious, and very loth to die. It lives by choice amongst the congregation of its fellows, in hot and dry soil. The ant works during summer, and gathers grain for food for the winter. And it splits the grain in two lest it should sprout and be spoiled, and be of no use when nothing can be gathered anymore. And it seeks no strange ways, but always goes forth by the same way. And if it abides its time, it shall be able to fly.
Thus should these men do. They should be strong in abiding the coming of Christ, sagacious against the communications and inspirations of the devil. They should not desire death; but God's glory alone, and for themselves new virtues. They should dwell in the congregation of their heart and of their powers, and should follow the drawing and the inviting of the Divine Unity. They should dwell in warm and dry soil, that is, in the fierce tumult of love and in a great restlessness. And they should labour during the summer of this life, and gather the fruits of virtue for eternity; and they should split these fruits in two. The one part is, that they should ever desire the most high fruition of Eternity; and the other part is that, by means of the reason, they should always restrain themselves as much as they can, and abide the time which God has ordained to them, and thus the fruit of virtue is preserved unto eternity. And they should not follow strange paths or singular ways; but they should follow the track of love through all storms to that place whither love shall lead them. And if they abide the time, and persevere in all virtues, they shall behold the Mystery of God and take flight towards It.
