The author says: Since we began in the previous treatise, with the various ways in which the Unity of G-d can be demonstrated so that it shall be wholeheartedly acknowledged, and we found that the examination of the wisdom manifested in the universe is the nearest way to clarify His existence and the clearest path to know His reality. [Therefore] we deem it our duty to deal with this theme, so that to each treatise, the one most nearly resembling it should be joined, and each topic should be followed by the most appropriate topic - this being among the subjects which we have to deal with in regard to the Almighty's service, the purpose for which we were created, as the wise man said (Kohelet 3:14) "And G-d has so made it that man should fear before Him".
בְּבֵאוּר אָפְנֵי הַבְּחִינָה בַּבְּרוּאִים וְרַב טוּב הָאֱלֹהִים עֲלֵיהֶם. וְזֶה פֶּתַח הַשַּׁעַר:
אָמַר הַמְחַבֵּר מִפְּנֵי שֶׁהִקְדַּמְנוּ בַּשַּׁעַר הָרִאשׁוֹן אָפְנֵי יִחוּד הָאֱלֹהִים בְּלֵב שָׁלֵם וְהָיְתָה הַבְּחִינָה בַּחָכְמָה הַנִּרְאֵית בִּבְרִיאַת הַבּוֹרֵא יִתְעַלֶּה הַדֶּרֶךְ הַקְּרוֹבָה אֶל בֵּרוּר מְצִיאוּתוֹ וְהַנְּתִיב הַסָּלוּל לָדַעַת אֲמִתָּתוֹ הִתְחַיַּבְנוּ לְהַדְבִּיקוֹ אֵלָיו כְּדֵי לִסְמֹךְ כָּל שַׁעַר אֶל מָה שֶׁהוּא דּוֹמֶה לוֹ מִן הַשְּׁעָרִים וּלְהָבִיא אַחַר כָּל עִנְיַן מָה שֶׁיֵּאוֹת לוֹ מִן הָעִנְיָנִים אֲשֶׁר בָּהֶם נִתְחַיֵּב בַּעֲבוֹדַת הָאֵל יִתְעַלֶּה אֲשֶׁר בְּרָאָנוּ לָהּ כמ״ש הֶחָכָם (קהלת ג) וְהָאֱלֹהִים עָשָׂה שֶׁיִּרְאוּ מִלְּפָנָיו.
