What are the seven great planes of cosmic conciousness?

The first chapter of The Perfect Matrimony mentions the seven great planes of cosmic conciousness. There, Master Samael mentions specifically the Astral, Mental, and Causal planes. What are the other four? An internet search turns up the wikipedia article in the references below, which cites Theosophical society writings. But they are saying that the mental and causal planes are two names for the same thing. Is the master Samael referring to the seven Sephiroth from Malkuth to Chesed or is the correspondence to Kabbalah not as simple as that?
