Aniruddha, a disciple of Śākyamuni Buddha, was named Wish Fulfilling when he was a child. The reason why he was so named was due to his ability to send down treasures as he wished. Asked how he became such a person, Śākyamuni Buddha answered: “It was due to the merit of offering a bowl of barnyard millet rice to a sage named Pratyekabuddha at a time of famine in the past.”
Also, Venerable Mahā-Kāśyapa was the most honorable priest in the world Jambudvīpa), second only to the Buddha. As a layman he was a wealthy person with 60 warehouses, each of which contained 140 koku (about 500 metric tons) of gold. He owned other treasures, too numerous to count. Asked about the previous life of Mahā-Kāśyapa and how he became such a wealthy person, Śākyamuni Buddha answered, “With the merit of offering a bowl of rice mixed with barley to a pratyekabuddha during a famine in the past, Mahā-Kāśyapa was reborn in the Trāyastriṃsá Heaven 1,000 times. Then he encountered Śākyamuni in this life, becoming foremost among His disciples, and was guaranteed to be a Buddha named Light Buddha in the future.” Thus, it is stated by Grand Master T’ien-t’ai in his Words and Phrases of the Lotus Sutra, fascicle one.
Contemplating the state of affairs today through the examples of Venerables Aniruddha and Mahā-Kāśyapa, isn’t it unreasonable to say that a bowl or rice cooked with barley offered by Venerable Mahā-Kāśyapa was so precious that the donor with its merit became the Light Buddha, but a bale of polished barley donated today does not have the same value and will not lead you to become a Buddha? This is impossible. The moon during the lifetime of the Buddha is the same as the moon today. The flower at the time of the Buddha is the same flower today. The merit of offering in the past remains the same today. Even more so, I am today a practicer of the Lotus Sūtra, despised by all the people in Japan, the ruler on top to his subjects below, and about to die of starvation. Feeling sorry for me, you kindly sent me articles of your goodwill all the way over the mountains and across rivers. They are not just barley and wheat but pieces of gold. They are not pieces of gold. They are the characters of the Lotus Sūtra. They look like barley and wheat to our human eyes, but the ten female rākṣasa demons will see the seed of Buddhahood in them.
