A client quotes some old channeling books with beings who claim they originate from the causal plane, which is above the astral, and have evolved beyond that into “multidimensional reality.” He wonders why the Source Creator I channel is only on the astral plane, or if this is disinformation? What can we tell him?

The information from these sources cannot be trusted. There is a mix of accurate and inaccurate information. They are overinflating their importance and the loftiness of their origin, so this entire representation is not a useful one. There are indeed many planes of existence that are beyond your understanding, so this represents esoteric lore of little practical value to you at the present time.
