大方便佛報恩經 1.55

1.55

"At that time, the king and queen succeeded in reaching the neighboring state. At that time, the king of that state went out far to welcome them, supplied whatever was needed, and granted everything according to their wishes. Then the great king explained to that king the causes and conditions of the previous events, of how his son's flesh had shown filial piety toward his parents, the matter being as it was. At that time, hearing these words, the king of the neighboring state was deeply moved by Crown Prince Sujāti being able to give up what is difficult to give up, offering his body's flesh and blood to his parents with such filial devotion. Moved by his compassion and filial piety, he immediately assembled the fourfold army and returned with that king to launch an expedition against Rāhula."
