Then his mind was perplexed with a variety of thoughts as to its substance and subsistence, the reason of its departure, etc. After much deliberation, at last he found that from that part of the heart which had departed proceeded all those actions by which the roe had shown her care of him and her affection,--that the body was only as an instrument or tool, like his cudgel with which he used to fight with the wild beasts. Thus all his regard for the body was over and transferred to that by which the body is governed, and by whose power it moves. So he decides in the end to bury the body. After its burial, the impression of his loneliness and of his dependence upon himself being deepened, he quickly develops his faculties. In a short time he becomes an expert in different sports, as hunting and fishing. He makes himself clothes and shoes of the skins of wild beasts. By the observations he made upon the swallows' nests, being taught the art of building, he builds with his hands a room for his own use, a store-house, and a pantry. Then he contrives to make some wild horses so tractable that he can use them for riding, which is a great help to him in his expeditions and excursions. His material existence thus once firmly established and secured, he begins to indulge in his speculations on all sorts of bodies,--on the different kinds of animals, plants, minerals and different sorts of stones, earth, water, exhalations and vapours, ice, snow, hail, smoke, fire, etc. By the time he attains to the age of twenty-eight (fourth Septenary), his mind starts to ponder over astronomical problems--over heaven and stars, sun and moon; and in the end comes to the conclusion that the body of heaven is finite and is of a spherical figure. At last his mind finds itself occupied with the great problem of Creation and Creator. With admirable skill the author delineates here the gradual development of Hayy's reasonings on the Creator and Mover of the world, and concludes with the panegyric words of the Koran: _He is the Existence, He is the Absoluteness, He is the Perfection, He is the Beauty, He is the Glory, He is the Power, He is the Knowledge, He is He, and all Things perish beside Him._ All his thoughts were henceforward confined to the contemplation of this necessarily self-existent Being. In order to do this, he removed all his affections from sensible things, shut his eyes, stopped his ears, and refrained himself as much as possible from following his imagination, endeavouring to the utmost to think of nothing besides him.
