R. Gikatilla made an original attempt to provide a detailed yet lucid and systematic exposition of kabbalism. He was also the originator of the doctrine equating the infinite, Ein Sof, with the first of the ten Sefirot. The conception was rejected by the majority of kabbalists from the 16th century onward, but his works continued to be highly esteemed and were published in many editions.
