ENLIGHTENMENT

The degree of one’s awareness of Reality.
[Note: The process of gaining enlightenment is the process of learning. Full enlightenment means possessing complete awareness of all that there is to be aware of — an imaginable but unattainable state (perhaps with rare exceptions, e.g., the Buddha, the enlightened one). On the backdrop of ignorance as the root cause of suffering, complete enlightenment is therefore synonymous with the cessation of suffering.]
