The mind consciousness's understanding cannot replace the manas's realization

If one has not genuinely realized the illusory and unreal nature of the six realms of rebirth, and has not genuinely realized that the five aggregates are without self, but merely has the mind consciousness understand and the mind consciousness believe it to be so, then it is just like an ostrich that buries its head in the sand, thinking that because it cannot see the enemy behind it, there is no danger. The gap between what we merely believe and what is actually realized through practice is enormous. It is like owing someone ten million and choosing to forget it, ignoring the matter—but is the creditor willing to let you off? Wishful thinking is absolutely unreliable. So when the mind consciousness believes the five aggregates are without self, it seems utterly certain, yet in reality there is still a self deep inside; it is only that one's wisdom is insufficient to discover it. What the mind consciousness understands and believes is merely wishful thinking, self-deception; it cannot substitute for genuine realization and is not utterly certain. Therefore, I once again urge those who place the highest importance on the mind consciousness: wake up quickly! The enterprise of the Path weighs heavier than Mount Tai, while reputation is lighter than a goose feather.
