What does it mean to say "Maitreya Buddha is really Maitreya Buddha, incarnating hundreds of millions"?

During the Kaiping period of Hou Liang in the Five Dynasties (907 ~ 9 1 1), a grotesque monk suddenly appeared in Fenghua, Siming, Zhejiang, with a wrinkled forehead and a big belly on his back. He begged everyone, begged everything and put it in his pocket. Strange to say, that pocket seems to have magic. No matter how many things are put in it, it is always unsatisfactory. Who is he? Where did it come from? No one knows, but there is something mysterious about him. Fortunately, Fenghua is simple and honest, and people see that his life is difficult. He will give anything he can if he asks. In this way, the strange monk lived in Fenghua. Because I don't know his name, people call him a "cloth bag monk" when I see him carrying a cloth bag all day. Although the cloth bag monk is strange, he also has many advantages: first, he is easy-going and doesn't beg very much. Generally, he only needs a penny. Second, he can predict personnel, and both good and bad luck are effective, so many people come to him for fortune telling every day. Bag monks are not afraid of trouble. As long as someone comes, he will definitely give someone a divination. Third, he gets along well with children, and often follows a large group of children and plays with him. In the eyes of children, everything is interesting. One day, they suddenly started fooling around and chased the cloth bag monk all over the street. They want to see what treasures are in the cloth bag of the cloth bag monk. The monk in the cloth bag was chased and had to dump his things in the street. What's the baby? They are just wooden shoes, fish and food, rubble and stones. The children were disappointed, but the interest of the cloth bag monk came. He picked up the things that fell to the ground one by one and kept saying, "What is this? Oh, it's a rice bowl. ""What is this? Oh, it's Meng Bi. " "What is this? Oh, tiles. " "What is this? Oh, bricks. " And so on, until he picked up the things on the ground, the words in his mouth were not finished. Finally, I got a lump of shit from somewhere, wrapped it in paper and said, "Oh, isn't this something from the inner court of Maitreya?" How did you get out? "Say also conveniently in the bag. This scared the children away. Once, a cloth bag monk stood on the road. Just as a monk passed by, the monk asked, "What are you doing standing here?" The cloth bag monk said, "I'm waiting for someone." The monk said, "Are you waiting for someone? Wait for me, I have arrived. " The cloth bag monk reached into his arms and took out an orange and handed it to him. As soon as the monk saw an orange to eat, he reached for it. The monk in the cloth bag drew back his hand and said, "Oh, you are not that person. Once again, a monk wanted to see what the cloth-bag monk had done and asked, "What is the purpose of the western Buddha?" The cloth bag monk put down his pocket and the fork hand stood there without saying a word. The monk asked again, "Only in this way, is there nothing else?" The monk put the cloth bag on his shoulder again and began to walk. Seeing that the other person was a crazy monk, the monk got up and left. I don't know. I just walked a few steps, and I felt someone touching my back. The monk looked back and saw that it was a cloth bag monk. The cloth bag monk reached out and said to him, "Give me a dollar!" " Who is the cloth bag monk? Only Fenghua Jiang Maha knows about it. Jiang Moho especially believes in Buddhism and has great respect for monks. In other people's eyes, although the cloth bag monk is bizarre, Jiang Moho finds it interesting to associate with him. Therefore, Jiang Maha became a friend of the cloth bag monk and often played with the cloth bag monk. After a long time, he knew that the cloth bag monk was originally called Qi Ben and had been to central Fujian. There is a Chen Jushi in the middle of Fujian who offered a thoughtful sacrifice to the cloth bag monk. Chen Jushi once asked him how old he was, and he replied, "My cloth bag is as big as vanity. It turned out that the cloth bag monk didn't want to stay in Fujian, so he came to Fenghua. Originally, Jiang Maha knew this until one day, he suddenly discovered the big secret of the cloth bag monk. That day, he and the cloth bag monk went to the river to take a bath and suddenly found a hole in the back of the cloth bag monk. Jiang Maha once thought of the hole behind the Buddha statue. He pointed to the cloth bag monk and said, "You are the Buddha." The monk in the cloth bag whispered to Jiang Maha, "Don't let anyone know. Since then, Jiang Maha has read the Maha Prajna Paramita Sutra with the cloth-bag monk, and did not dare to publicize the fact that the cloth-bag monk is a Buddha. In the second year of Zhenming (9 16), a monk in a cloth bag sat on the east corridor of Lin Yue Temple, leaving a note before he died, saying, "Maitreya is really Maitreya, incarnating hundreds of millions; Always shows the time when people don't know. People buried him in the mountains. It is said that after he was buried, people still saw him in the street. He said to someone, "I accidentally brought my shoelaces, so I have to return them quickly." Say that finish and left. When the man got home, he realized that the cloth-bag monk was dead, so he told the story of seeing the cloth-bag monk on the road.
