Ancient Buddhist Scriptures

If a Buddha sacrifices his body and becomes a demon, how can he be a Buddha?  Immortal, if he transforms into a demon by bathing in blood, what kind of immortal should he be?  Demon, if you put down your butcher knife, can you still become a Buddha?  Demon, if you give up your original intention, can you embark on the path to immortality?  Good and evil are true and false, in this mortal world, where is the Tao?  ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​…  Buddha and demon, in one thought, one leaf blinds the eyes.
