“Seth material” search engine (Jane Roberts)

These outposts were constructed underground. From the original cities and large settlements there were, of course, underground connections, a system of tunnels, highly intricate and beautifully engineered. Since these were an aesthetic people, the walls were lined with paintings and drawings, and sculpture was also displayed along these inner byways.

I should perhaps mention here that some of the caves, particularly in certain areas of Spain and the Pyrenees, and some earlier ones in Africa, were artificial constructions. Now these people moved mass with sound, and, as I told you earlier, actually conveyed matter through a high mastery of sound. This is how their tunnels were originally formed, and it was also the method used to form some of the caves in areas where originally there were few. Often drawings on the cave walls were highly stylized information, almost like signs in your terms in front of public buildings, portraying the type of animals and beings in a given area.
