The GENERAL CONTEXT of such use is:
The term refers to all of the "tools" and "factors" that do constitute the barriers - the Veil of Separation or the Veil of Unknowing - which Satan has influenced humanity to create in human society, in order to prevent each and all from actualizing their innate and extant maturity of mind, which would allow an individual to actually know Who and What one is, as well as allowing access to the Soul and those dimensions of consciousness beyond the (s)elf.
