What Is Enlightenment? According to Immanuel Kant; Enlightenment is man’s emergence from his self-imposed immaturity. Immaturity is the inability to use one’s understanding without guidance from another. This immaturity is self-imposed when its cause lies not in lack of understanding, but in lack of resolve and courage to use it without guidance from another. Sapere Aude! [dare to know] “Have courage to use your own understanding!”–that is the motto of enlightenment.
In Buddhism, enlightenment (called bodhi in Indian Buddhism, or satori in Zen Buddhism) is when a Buddhist finds the truth about life and stops being reborn. Buddhists believe a person can become enlightened by following the Middle Way.
I feel it is a bit different than these, more of an awakening process that leads to an authentic way of living and being.
