Wallis asserts that cults emerge from the "cultic milieu". In 392 Theodosius passed legislation prohibiting all pagan cultic worship. Performance of cultic or missionary activities or religious processions on public ground may be limited. Sacred areas often had a guardian or a performer of cultic rites. High places were prevalent in almost all ancient cultures as centers of cultic worship. Corridors were used as "favissae" (deposits of cultic artifacts) to store bones after ritual sacrifice. Sun amulets were widespread as cultic ornaments. Artifacts of potential cultic significance were found around the temple. It was in this cultic milieu that Narendra became acquainted with Western esotericism. The environment is cultic, sometimes sectarian. Another riddle is the original cultic and symbolic function of the Sphinx. The entrance pillars appear to have architectural and cultic significance. It is likely a literary conceit, not a cultic epithet. He himself has been raised, like a medieval saint, to a figure of cultic status. Other subjects he has researched include mind control and cultic behavior.
