Why Use Pointers?
The term 'Realization' (or waking up, or enlightenment) is used to express a major shift where the normal reality is no longer seen to be reality, but rather is now seen to be only a story, only conceptual, only imaginary, like a daydream. The new reality can be known but not described because the only tools for communicating are in the previous normal reality which uses words and ideas and sentence structures that assume separate subjects, and separate objects. The new reality cannot be described in these old terms because the new reality has no separate subjects, no separate objects, no separation at all. So words and phrases are used as "Pointers" to point to this new reality that has no separation.
Do not mistake the pointing finger for the moon.
