Pardes Rimmonim, Author's Introduction

We have divided the scroll into thirty-two parts, calling them Gates, as they are gateways into the inner depths and secrets of Torah. We further divided the gates into chapters, some short, some long, according to the nature of the teachings within each chapter. We implore the reader not to enter these gates unless they possess the keys and understand the ways of the gates, for without them, harm rather than benefit may result. Those who have received the keys will find many, many doors opened to them in this wisdom.
