Buddha

Siddhārtha Gautama and Buddha Shakyamuni

Buddha, "Awakened One" or "Enlightened One", is the masculine form of budh (बुध् ), "to wake, be awake, observe, heed, attend, learn, become aware of, to know, be conscious again", "to awaken" "'to open up' (as does a flower)", "one who has awakened from the deep sleep of ignorance and opened his consciousness to encompass all objects of knowledge". It is not a personal name, but a title for those who have attained bodhi (awakening, enlightenment). Buddhi, the power to "form and retain concepts, reason, discern, judge, comprehend, understand", is the faculty which discerns truth (satya) from falsehood.
