Terence Mckenna - Totality Symbol

Symbol always "points beyond itself" to something that is unquantifiable and mysterious. This is the symbol's "depth dimension". Symbols are complex and their meanings can evolve as the individual or culture evolves. When a symbol loses its meaning and power for an individual or culture, it becomes a dead symbol. The Greek Gods might be an example of dead symbols that were once living for the ancient Greeks but whose meaning and power is now gone.

When a symbol becomes identified with the deeper reality to which it refers, it becomes idolatrous as the "symbol is taken for reality." Here, the symbol itself is substituted for the deeper meaning it intends to convey. The unique nature of the symbol is that it gives access to deeper layers of reality which are otherwise inaccessible.
