For example, in a garden of that All-Glorious and Compassionate One's munificence, I counted the bunches hanging from a grape-vine of the thickness of two fingers, which I saw to be like one little pip among the bunches of His miracles: there were one hundred and fifty-five. I counted the grapes in one bunch: there were around one hundred and twenty. I thought: if this vine was a tap from which flowed honeyed water and it produced water continuously, it would only just be enough for the bunches which, in the face of this heat, suckle those hundreds of little pumps of the sherbet of mercy. However, it only occasionally obtains a little moisture. The One Who does this, then, must surely be powerful over all things. Glory be to Him at Whose art minds are bewildered!
Look! With little difficulty you can see the seals of the Single, Eternally Besought One on the page of the earth, so raise your head, open your eyes, and look too at the great book of the universe. You will see that on it as a whole a stamp of unity is read out which is as clear as it is big. For like the components of a factory or members of a palace or town, these beings support one another, stretch out their hands to assist one another, and answer the needs and requests of one another, saying: "Here I am, at your service!" Assisting one another, they work together in order. Joining efforts, they serve animate beings. Co-operating and turned a single goal, they obey an All-Wise Disposer. They conform to a rule of mutual assistance which is in force from the sun and moon, night and day, and winter and summer, to plants coming to the assistance of hungry and needy animals, and animals hastening to the assistance of weak, noble men, and even nutritious substances flying to assist delicate, weak infants and fruits, and particles of food passing to the assistance of the cells of the body. They show to anyone who is not altogether blind that they are acting through the strength of a single, most generous Nurturer, and at the command of a single most wise Disposer.
Thus, on the one hand this mutual support and assistance, this answering one another's needs, this mutual embracing, this subjugation, this order, testify decisively that beings are administered and organized by a single Disposer and are being impelled and directed by a single Nurturer. And on the other hand, this perfect grace within the universal wisdom to be seen plainly in the art of things; and the all-embracing mercy which shines within the providence; and the sustenance spread over that mercy and scattered so as to answer the needs of all living beings needy for sustenance; —these form a stamp of Divine unity so brilliant that anyone whose mind is not altogether extinguished will understand it and anyone who is not altogether blind will see it.
