Sixth window: Consider the following verse:

In the creation of the heavens and Earth; in the alternation of night and day; in the sailing of the ships through the ocean for the benefit of humanity; in the water which God sends down from the sky and with which He revives Earth after its death, and dispersing over it all kinds of beasts; in the ordinance of the winds and clouds that are driven between Earth and sky, are signs for people who have sense and use their reason. (2:164)

This verse, which demonstrates God's necessary Existence and Unity, is an extremely large window through which one of God's Greatest Names is seen. Briefly, all worlds situated at the universe's various levels point to the same result in different tongues: the Lordship of a single Wise Maker. Just as well‑organized and systematic movements in the heavens end in great results and thereby show a Majestic All‑Powerful One's Existence and Unity and His Lordship's perfection, the tremendous seasonal and other changes we see on Earth result in great, comprehensive benefits and thereby show the necessity of that Majestic All‑Powerful One's Unity and His Lordship's perfection.

All land and water animals are fed through perfect mercy, given forms with perfect wisdom, and equipped with senses and faculties through perfect Lordship. Each testifies to that Majestic All‑Powerful One's Existence and points to His Unity. As a whole, they demonstrate His Divinity's grandeur and His Lordship's perfection on a large scale. Similarly, all well‑formed plants in gardens and orchards and their ornate flowers, the well‑proportioned fruits that replace the flowers, and the rich embellishments displayed by the fruits bear witness to that All‑Wise Maker's Existence and point to His Unity individually. Collectively, they show His Mercy's grace and His Lordship's perfection in a splendid way.

All drops sent from the atmosphere and charged with important purposes, necessary consequences, and benefits show that All‑Wise Maker's necessary Existence and Unity and His Lordship's perfection. In the same way, all mountains and minerals deposited in them for various purposes show that Wise Maker's Existence and Unity and His Lordship's perfection. All beautiful flowers decorating hills and plains individually attest to an All‑Wise Maker's necessary Existence and point to His Unity. Collectively, they show His Sovereignty's majesty and His Lordship's perfection. All well‑proportioned shapes and positions of herb and tree leaves, as well as their rapturous and systematic movements, show that All‑Wise Maker's necessary Existence and Unity and His Lordship's perfection.

All growing bodies have been innately equipped with various members and systems to grow. At the time of growth, they begin to move in an ordered manner and are directed toward yielding fruits. Each one testifies to that All‑Wise Maker's necessary Existence and points to His Unity. As a whole, they demonstrate His Power's comprehensiveness, His Wis‑dom's inclusiveness, His art's beauty, and His Lordship's perfection on a very large scale. Establishing souls and spirits in all animal bodies with perfect wisdom, equipping them with appropriate systems with perfect order, and mobilizing them for unique services and purposes with perfect wisdom—all of this bears witness and points to that All‑Wise Maker's necessary Existence and Unity. Collectively, these acts show His Mercy and His Lordship's perfection in a most brilliant way.

All Divine inspirations that instruct humanity in knowledge and truth, as well as teach animals how to procure their needs, suggest the Existence of a Most Compassionate Lord and point to His Lordship. Also, like rays of light coming from the eye and collecting together all visible objects each of which is a "flower" in the garden of the universe, each outer and inner sense functions as a key to a different world. This demonstrates, as brightly as the sun, the necessary Existence of that All‑Wise Maker, All‑Knowing Originator, Most Compassionate Creator, All‑Munificent Provider, and His Unity and Lordship's perfection.

Thus the huge window consisting of 12 openings in 12 places shows 12 colors of Almighty God's Oneness and Uniqueness and His Lordship's perfection through a light of truth. How can you close that window, which is as wide as Earth or even its orbit? How can you extinguish that source of light, which is as bright as the sun? Behind what veil of heedlessness can you hide it?
