A true encyclopedia of the sacred names and the wisdom of the Sefirot, The Gates of Light (Shaarei Orah) is a basic book for entering into the study of the Torah using the techniques of the Kabbalists. At the beginning of his book, Yosef Gikatilla explains that the entire Torah is woven by the name of the Eternal, and that "he who understands the meanings of all the holy names and of those who are linked with them and each of their denominations, will discover that everything depends on his great blessed name, and will aspire to be linked to it and to fear it". Divided into ten Gates, each one of them preceded by a psalm, this extraordinary and systematic book gives us an exposition of the names of God, associating them to the ten Sefirot.
