“When a man reflects on these things, studies all these created beings, from the angels and spheres down to human beings and so on, and realizes the divine wisdom manifested in them all, his love for God will increase, his soul will thirst, his very flesh will yearn to love God.”
Book 1 (Sefer HaMadda'<!--[sic]-->), 4.12
Mishneh Torah (c. 1180)
Context: When a man reflects on these things, studies all these created beings, from the angels and spheres down to human beings and so on, and realizes the divine wisdom manifested in them all, his love for God will increase, his soul will thirst, his very flesh will yearn to love God. He will be filled with fear and trembling, as he becomes conscious of his lowly condition, poverty, and insignificance, and compares himself with any of the great and holy bodies; still more when he compares himself with any one of the pure forms that are incorporeal and have never had association with any corporeal substance. He will then realize that he is a vessel full of shame, dishonor, and reproach, empty and deficient.

Entry in Tolstoy's Diary http://www.linguadex.com/tolstoy/chapter1.htm (1 November 1910)
Context: God is the infinite ALL. Man is only a finite manifestation of Him.
Or better yet:
God is that infinite All of which man knows himself to be a finite part.
God alone exists truly. Man manifests Him in time, space and matter. The more God's manifestation in man (life) unites with the manifestations (lives) of other beings, the more man exists. This union with the lives of other beings is accomplished through love.
God is not love, but the more there is of love, the more man manifests God, and the more he truly exists...
We acknowledge God only when we are conscious of His manifestation in us. All conclusions and guidelines based on this consciousness should fully satisfy both our desire to know God as such as well as our desire to live a life based on this recognition.
