The teaching of the Buddha constitutes the Buddhadharma. The word Buddha, in Sanskrit, means the Enlightened One. Simply stated, Buddha is an enlightened person. After he attained enlightenment, his teaching became known as the Buddhadharma. The Buddhadharma is the collected words, teaching and action of the Enlightened One. The Buddhadharma also discloses his expedient way to save all living beings. Therefore, the sutra says: "The Buddha is a person who enlightened himself, enlightened others and ultimately attained Complete Enlightenment." Usually, we say we study the Buddhadharma, which means that we learn the way to enlighten ourselves, to enlighten others and to reach Complete Enlightenment. If one arrives at this stage, then he is an Enlightened One, a Buddha. The purpose and goal of learning the Buddhadharma is based on the desire to become a Buddha. The Buddha taught people to practice the highest wisdom, which is perfect and enables a person to transcend the human stage or level. The Buddha is a perfect, great Enlightened One. Therefore, the Buddhadharma is also known as the teaching of Great Enlightenment. Furthermore, the Buddha is a perfect person of great and total compassion, and he is one who uses the mind of great compassion to convert all sentient beings. Without great enlightenment, one cannot talk about perfect wisdom; without great compassion, one cannot talk about the transcendent, totally realized personality. Also, to use the truth of the Buddhadharma in action, we must employ perfect wisdom.
