Spiritual Characteristics:
Know thou that every created thing is a sign of the revelation of God. Each, according to its capacity, is, and will ever remain, a token of the Almighty. Inasmuch as He, the sovereign Lord of all, hath willed to reveal His sovereignty in the kingdom of names and attributes, each and every created thing hath, through the act of the Divine Will, been made a sign of His glory. So pervasive and general is this revelation that nothing whatsoever in the whole universe can be discovered that doth not reflect His splendor. Under such conditions every consideration of proximity and remoteness is obliterated…. Were the Hand of Divine power to divest of this high endowment all created things, the entire universe would become desolate and void.
(Baha’u’llah: Gleanings, p. 184)

How all-encompassing are the wonders of His boundless grace! Behold how they have pervaded the whole of creation. Such is their virtue that not a single atom in the entire universe can be found which doth not declare the evidences of His might, which doth not glorify His holy Name, or is not expressive of the effulgent light of His unity. So perfect and comprehensive is His creation that no mind nor heart, however keen or pure, can ever grasp the nature of the most insignificant of His creatures;…
(Baha’u’llah: Gleanings, p. 62)

Nature in its essence is the embodiment of My Name, the Maker, the Creator. Its manifestations are diversified by varying causes, and in this diversity there are signs for men of discernment. Nature is God’s Will and is its expression in and through the contingent world. It is a dispensation of Providence ordained by the Ordainer, the All-Wise.
(Baha’u’llah: Tablets of Baha’u’llah, p. 142)

I am well aware, O my Lord, that I have been so carried away by the clear tokens of Thy loving-kindness, and so completely inebriated with the wine of Thine utterance, that whatever I behold I readily discover that it maketh Thee known unto me, and it remindeth me of Thy signs, and of Thy tokens, and of Thy testimonies. By Thy glory! Every time I lift up mine eyes unto Thy heaven, I call to mind Thy highness and Thy loftiness, and Thine incomparable glory and greatness; and every time I turn my gaze to Thine earth, I am made to recognize the evidences of Thy power and the tokens of Thy bounty. And when I behold the sea, I find that it speaketh to me of Thy majesty, and of the potency of Thy might, and of Thy sovereignty and Thy grandeur. And at whatever time I contemplate the mountains, I am led to discover the ensigns of Thy victory and the standards of Thine omnipotence.
(Baha’u’llah: Prayers and Meditations, pp. 271-272)

Look at the world and ponder a while upon it. It unveileth the book of its own self before thine eyes and revealeth that which the Pen of thy Lord, the Fashioner, the All-Informed, hath inscribed therein. It will acquaint thee with that which is within it and upon it and will give thee such clear explanations as to make thee independent of every eloquent expounder.
(Baha’u’llah: Tablets of Baha’u’llah, pp. 141-142)

Likewise, look into this endless universe: a universal power inevitably existeth, which encompasseth all, directing and regulating all the parts of this infinite creation; and were it not for this Director, this Co-ordinator, the universe would be flawed and deficient. It would be even as a madman; whereas ye can see that this endless creation carrieth out its functions in perfect order, every separate part of it performing its own task with complete reliability, nor is there any flaw to be found in all its workings. Thus it is clear that a Universal Power existeth, directing and regulating this infinite universe.
(`Abdu’l-Baha: Selections … `Abdu’l-Baha, pp. 48-49)

Physical Characteristics:
Know assuredly that God’s creation hath existed from eternity, and will continue to exist forever.
(Baha’u’llah: Gleanings, p. 150)

Now concerning nature, it is but the essential properties and the necessary relations inherent in the realities of things. And though these infinite realities are diverse in their character yet they are in the utmost harmony and closely connected together.
(`Abdu’l-Baha: Tablet to August Forel, p. 20)

The worlds of God are in perfect harmony and correspondence one with another. Each world in this limitless universe is, as it were, a mirror reflecting the history and nature of all the rest. The physical universe is, likewise, in perfect correspondence with the spiritual or divine realm. The world of matter is an outer expression or facsimile of the inner kingdom of spirit. The world of minds corresponds with the world of hearts.
(`Abdu’l-Baha: Promulgation of Universal Peace, p. 270)

But I mean that this limitless universe is like the human body, all the members of which are connected and linked with one another with the greatest strength. How much the organs, the members and the parts of the body of man are intermingled and connected for mutual aid and help, and how much they influence one another! In the same way, the parts of this infinite universe have their members and elements connected with one another, and influence one another spiritually and materially.
For example, the eye sees, and all the body is affected; the ear hears, and all the members of the body are moved. Of this there is no doubt; and the universe is like a living person. Moreover, the connection which exists between the members of beings must necessarily have an effect and impression, whether it be material or spiritual.
(`Abdu’l-Baha: Some Answered Questions, pp. 245-246)

Nature is that condition, that reality, which in appearance consists in life and death, or, in other words, in the composition and decomposition of all things.
This Nature is subjected to an absolute organization, to determined laws, to a complete order and a finished design, from which it will never depart – to such a degree, indeed, that if you look carefully and with keen sight, from the smallest invisible atom up to such large bodies of the world of existence as the globe of the sun or the other great stars and luminous spheres, whether you regard their arrangement, their composition, their form or their movement, you will find that all are in the highest degree of organization and are under one law from which they will never depart.
(`Abdu’l-Baha: Some Answered Questions, p. 3)

Man and Nature:
But when you look at Nature itself, you see that it has no intelligence, no will. For instance, the nature of fire is to burn; it burns without will or intelligence. The nature of water is fluidity; it flows without will or intelligence. The nature of the sun is radiance; it shines without will or intelligence. The nature of vapor is to ascend; it ascends without will or intelligence. Thus it is clear that the natural movements of all things are compelled; there are no voluntary movements except those of animals and, above all, those of man. Man is able to resist and to oppose Nature because he discovers the constitution of things, and through this he commands the forces of Nature; all the inventions he has made are due to his discovery of the constitution of things.
(`Abdu’l-Baha: Some Answered Questions, pp. 3-4)

It is evident, therefore, that man is ruler over nature’s sphere and province. Nature is inert; man is progressive. Nature has no consciousness; man is endowed with it. Nature is without volition and acts perforce, whereas man possesses a mighty will. Nature is incapable of discovering mysteries or realities, whereas man is especially fitted to do so. Nature is not in touch with the realm of God; man is attuned to its evidences. Nature is uninformed of God; man is conscious of Him. Man acquires divine virtues; nature is denied them. Man can voluntarily discontinue vices; nature has no power to modify the influence of its instincts. Altogether it is evident that man is more noble and superior, that in him there is an ideal power surpassing nature. He has consciousness, volition, memory, intelligent power, divine attributes and virtues of which nature is completely deprived and bereft; therefore, man is higher and nobler by reason of the ideal and heavenly force latent and manifest in him.
(`Abdu’l-Baha: Promulgation of Universal Peace, p. 178)

In creation there is no evil; all is good. Certain qualities and natures innate in some men and apparently blameworthy are not so in reality. For example, from the beginning of his life you can see in a nursing child the signs of greed, of anger and of temper. Then, it may be said, good and evil are innate in the reality of man, and this is contrary to the pure goodness of nature and creation. The answer to this is that greed, which is to ask for something more, is a praiseworthy quality provided that it is used suitably. So if a man is greedy to acquire science and knowledge, or to become compassionate, generous and just, it is most praiseworthy. If he exercises his anger and wrath against the bloodthirsty tyrants who are like ferocious beasts, it is very praiseworthy; but if he does not use these qualities in a right way, they are blameworthy.
(`Abdu’l-Baha: Some Answered Questions, p. 215)

Briefly, it is not only their fellow human beings that the beloved of God must treat with mercy and compassion, rather must they show forth the utmost loving-kindness to every living creature. For in all physical respects, and where the animal spirit is concerned, the selfsame feelings are shared by animal and man. Man hath not grasped this truth, however, and he believeth that physical sensations are confined to human beings, wherefore is he unjust to the animals, and cruel.
And yet in truth, what difference is there when it cometh to physical sensations? The feelings are one and the same, whether ye inflict pain on man or on beast. There is no difference here whatever. And indeed ye do worse to harm an animal, for man hath a language, he can lodge a complaint, he can cry out and moan; if injured he can have recourse to the authorities and these will protect him from his aggressor. But the hapless beast is mute, able neither to express its hurt nor take its case to the authorities. If a man inflict a thousand ills upon a beast, it can neither ward him off with speech nor hale him into court. Therefore is it essential that ye show forth the utmost consideration to the animal, and that ye be even kinder to him than to your fellow man.
Train your children from their earliest days to be infinitely tender and loving to animals. If an animal be sick, let the children try to heal it, if it be hungry, let them feed it, if thirsty, let them quench its thirst, if weary, let them see that it rests.
(`Abdu’l-Baha: Selections … `Abdu’l-Baha, pp. 158-159)

The Earth:
Every man of discernment, while walking upon the earth, feeleth indeed abashed, inasmuch as he is fully aware that the thing which is the source of his prosperity, his wealth, his might, his exaltation, his advancement and power is, as ordained by God, the very earth which is trodden beneath the feet of all men.
(Baha’u’llah: Epistle to the Son of the Wolf, p. 44)

But it is clear that this terrestrial globe in its present form did not come into existence all at once, but that this universal existence gradually passed through different phases until it became adorned with its present perfection. Universal beings resemble and can be compared to particular beings, for both are subjected to one natural system, one universal law and divine organization. So you will find the smallest atoms in the universal system are similar to the greatest beings of the universe. It is clear that they come into existence from one laboratory of might under one natural system and one universal law; therefore, they may be compared to one another. Thus the embryo of man in the womb of the mother gradually grows and develops, and appears in different forms and conditions, until in the degree of perfect beauty it reaches maturity and appears in a perfect form with the utmost grace. And in the same way, the seed of this flower which you see was in the beginning an insignificant thing, and very small; and it grew and developed in the womb of the earth and, after appearing in various forms, came forth in this condition with perfect freshness and grace. In the same manner, it is evident that this terrestrial globe, having once found existence, grew and developed in the matrix of the universe, and came forth in different forms and conditions, until gradually it attained this present perfection, and became adorned with innumerable beings, and appeared as a finished organization.
(`Abdu’l-Baha: Some Answered Questions, pp. 182-183)

Life on Other Planets:
Verily I say, the creation of God embraceth worlds besides this world, and creatures apart from these creatures.
(Baha’u’llah: Gleanings, p. 152)

Know thou that every fixed star hath its own planets, and every planet its own creatures, whose number no man can compute.
(Baha’u’llah: Gleanings, p. 163)
