The following "Simple Definition of Buddhism" is selected from the Spirit and Characteristics of Buddhism by Professor Lin Shimin.
Simply define Buddha: the' Buddha' I want to introduce to you here is the general meaning of infinite buddhas and is broad. I try to define "Buddha" as follows:
Buddha is a personality whose reason, emotion and ability all reach the most perfect state at the same time. I repeat:' Buddha' is a personality whose reason, emotion and ability reach the most satisfactory state at the same time. In other words, the Buddha is a person with great wisdom, great compassion (or all-wisdom and all-compassion) and great strength. Please pay attention to the difference between Buddhism and other religions: Buddha is not omnipotent, and he can't free us. He can only teach us, and we still have to rely on our own efforts to get rid of it. Buddha can't let us go to heaven or condemn us to hell. It is really not an easy task to define' Buddha'.
Simply put, the Buddha is the awakened one, the awakened one.
Perhaps more clearly, it should be said that Buddha is a person who has a thorough understanding of the fundamental principles of life in the universe.
There is also a concise definition, which is generally accepted by ordinary people, that is to say, Buddha is a person who consciously realizes him and achieves perfection. In other words, Buddha is a person who has realized himself and can further help others to realize himself, and this self-awareness and cognition of his own work have reached the most satisfactory state at the same time.
