This, O Son, is the concealed stone of many colours, which is born and brought forth in one colour; know this and conceal it. By this, the Almighty favouring, the greatest diseases are escaped, and every sorrow, distress, and evil and hurtful thing is made to depart; for it leads from darkness into light, from this desert wilderness to a secure habitation, and from poverty and straits to a free and ample fortune.
