Moses de León / Moshé ben Shem-Tob de León
Sefer Ha-Rimmon / The Book of the Pomegranate1285
Everything is linked with everything else down to the lowest ring of the chain, and the true essence of God is above as well as below, in the heavens as well as on the earth, and nothng exist outside Him. And this is what the sages mean when they say: when God gave the Torah to Israel he opened the seven heavens and they saw nothing was there in reality butHis Glory; He opened the seven worlds to them and they saw that nothing was there but His Glory; He opened the seven abysses before their eyesm and they saw that nothing was there but His Glory. Meditate on these things and you will understand that God’s essence in linked and connected to all the worlds, and that all forms of existence are linked and connected with each other, but derived from Her existence.
