I offer an explanation that one of my theology professors, whose expertise was Christian-Buddhist relations, gave me. This is heavily simplified, but bear with me:
Eastern religions are fundamentally based on a different theory of reality than the West. In ancient Greece, there was a debate between two schools of philosophy. The followers of Heracleitus argued that the reality is in flux, and change is an illusion (pluralism); whereas the followers of Parmenides argued that reality is of a single substance, and difference is an illusion (monism). These particular philosophies are extremes, but generally, a moderated form of monism became adapted by Aristotle, which became the norm in Western philosophy.
It's the exact opposite in Eastern philosophy; reality is a process more than a web of things. Hence the parable of how life is like a candle wick, constantly in change but approaching its source as time goes on.
