the inherent attributes of his soul;
the influence of his heritage;
the impressions of his surroundings; and lastly
the impression of himself and of his thoughts and deeds, of the clothes he wears, the food he eats, the air he breathes, and the way he lives.

In the first of these sources man is helpless for he has no choice. It was not the desire of the tiger to be a tiger, neither did a monkey choose to be a monkey, and it was not the choice of the infant to be born a male or a female. This proves that the first source of man's form depends upon the inherent attributes brought by his soul. Words never can express adequately the wisdom of the Creator who not only fashioned and formed the world, but has given to each being the form suited to his needs. The animals of the cold zone are provided with thick fur as a protection against the cold; to the beasts of the tropics a suitable form is given; the birds of the sea have wings fit for the sea, and those of the earth are provided with wings suitable for the earth. Birds and animals have forms which accord with their habits in life. The form of man proclaims his grade of evolution, his nature, his past and present, as well as his race, nation and surroundings, character and fate.
In the second instance man inherits beauty or its opposite from his ancestors, but in the third and fourth his form depends upon how he builds it.
The build of his form depends upon the balance and regularity of his life, and upon the impressions he receives from the world; for in accordance with the attitude he takes towards life his every thought and action adds, or takes away, or removes to another place the atoms of his body, thus forming the lines and muscles of form and feature. For instance the face of a man speaks his joy, sorrow, pleasure, displeasure, sincerity, insincerity, and all that is developed in him. The muscles of his head tell the phrenologist his condition in life. There is a form in the thoughts and feelings which produces a beautiful or ugly effect.

It is the nature of evolution for all beings, from the lowest to the highest stage of manifestation, to evolve by being connected with a more perfect form. Animals approaching man in their evolution resemble primitive man, and animals in contact with man acquire in their form traces of the likeness of man. This may be understood by a close study of the features of man in the past, and of the improvement which has been made in them.
The nature of creation is that it is progressing always towards beauty. "God is beautiful, and He loves beauty", says the Qur'an. The nature of the body is to beautify itself; the nature of the mind is to have beautiful thoughts; the longing of the heart is for beautiful feelings. Therefore an infant should grow more beautiful every day, and ignorance seeks to become intelligence. When the progress is in a contrary direction, it shows that the individual has lost the track of natural progress. There are two forms: the natural and the artificial, the latter being a copy of the former.
