Shakyamuni while in the Causal Stages (of Bodhisattvahood) Performs the Filial Act of Gouging Out His Eyes and Marrow for the Sake of a Cure
The Great Canon states: The prince of Ksanti knew his father the king’s body was hampered by a serious illness and gave the order to seek a means of cure morning and night. The prince would ask, “What will cure him?” The great ministers replied, “It is the eyes and marrow of a person who doesn’t anger. If this medicine is obtained, the illness should be cured.” The prince said, “Take my marrow.” At that time, the great statesmen accepted and the medicine entered the king. It promptly cured the king’s illness. The prince’s life came to an end. Using sandalwood, they raised a pagoda for his bones and made an offering. Hence, we know that the Thus Come One’s filial conduct in repaying kindness brought so much salvation in that kalpa, it is beyond thought or description.
