Why am I doing this?

There are (technically) no lies, only a lack of truth. This is because the person who has been lied to is given a limited framework in which to operate, and doesn't see the bigger picture. There human consciousness is separate from reality, without necessarily being apart from it in any way. The mind exists in reality, but is limited by the laws of physics from experiencing transcendence. "Untruth", on the other hand, is an abstract realm that doesn't conform to the structure of reality, and is thus unreal (residing in unreality).

Reality is an illusion. There is only the perception of reality, which is ultimately subjective. You experience the cascade of different phenomena interpreted by your mind and processed into meaningful information. Your interpretation of reality is what ultimately creates reality as you experience it subjectively. There is no objective reality, just as there are no separate objects. There is only your perception of reality, which is how you interpret it.

If you think you know everything, you know nothing.
