Based on a series of lectures that Rabbi Aryeh Kaplan gave to a small group of students in Brooklyn in 1981, this contains transcripts of the series on the Kabbalistic system, and testifies to his wonderful ability to transmit profound ideas in a readily-graspable way. Although this is an introductory text, it contains many perspectives that are expressed in a unique way, so it would be quite valuable even for the more advanced student of Jewish mysticism.

Collected essays on Jewish themes.

This essay is an examination of the age of the universe as discussed in Kabbalistic works. It is important to realize that the Kabbalistic texts do not only discuss mysticism, but also many areas of hashkafah (Jewish outlook) which are of great importance to us. Let us begin with the classic question asked about the age of the universe. At face value, the Torah seemingly teaches us that the universe is 6,000 years old. Therefore, many people would hold the opinion that anyone who believes that the world is older than 6,000 years is an apikores(one who denies the basic tenets of Judaism). However, there is scientific evidence that the universe is more than 6,000 years old; maybe millions of times more. How do we resolve this question?

Three of Rabbi Aryeh Kaplan's notable essays: If You Were G-d, Immortality and the Soul, and A World of Love.

Students of mediation are usually surprised to discover that a Jewish mediation tradition exists and that it was an authentic and integral part of mainstream Judaism until the eighteenth century. Jewish Meditation is a step-by-step introduction to meditation and the Jewish practice of meditation in particular. This practical guide covers such topics as mantra meditation, contemplation, and visualization within a Jewish context. It shows us how to use meditative techniques to enhance prayer using the traditional liturgy—the Amidah and the Shema. Through simple exercises and clear explanations of theory, Rabbi Kaplan gives us the tools to develop our spiritual potential through an authentically Jewish meditative practice.
