A Buddha is One Who Continue to Strive
A Buddha is a person who continues to strive in the real world based on the Mystic Law, guided by the belief that their own life and the lives of others are infinitely valuable and respect worthy.
What distinguishes a Buddha from an Unenlightened person is the unshakeable conviction that our inner potential is as vast as the universe itself. When we awaken to this truth, we will not be defeated by even the most challenging environment and will be able to make the place where we are right now shine as the Land of Tranquil Light.
