I remember watching a lecture by a Kabbalist named Wolf about four years ago. He described a lot of interesting similarities between Eastern religions (including Buddhism and other Indian religions) and Judaism. There was apparently a lot of cross-pollination. One of the more interesting things I remember him saying was the interesting link, linguistically speaking, between "Abrah(a)m" and "Brahma(n)". And the mention in the Torah that Abraham journeyed to the East with his sons or something (horrible paraphrase...).
Sorry not to have replied to this thread sooner. Yes, there are lots of connections. Having studied both Qaballa & Vedanta, I find that very often the only difference is the words they use to describe phenomena. In many occult books I have seen images of the Tree of Life with the Seven Yoga Chakras worked into it. Every principle that you can find in the Vedic Teachings, has a correspondance somewhere on the Qaballistic Tree of Life.
