A florist, named Sumana, had to supply King Bimbisara of Rajagaha with jasmine flowers every morning. One day, as he was going to the king’s palace he saw the Buddha, with a radiating halo of light-rays, coming into town for alms-food accompanied by many monks. Seeing the Buddha in his resplendent glory, the florist Sumana felt a strong desire to offer his flowers to the Buddha. Then and there, he decided that even if the king were to drive him out of the country or to kill him, he would not offer the flowers to the king for that day.
The wife of the florist Sumana then went to the king and said that she had nothing to do with her husband failing to supply the king with flowers for that day The king, being a sotàpanna(person who has seen the Dharma) himself, felt quite happy about the flowers. He came out to see the wonderful sight and paid obeisance to the Buddha. The king also took the opportunity to offer almsfood to the Buddha and his disciples. The king served the congregation of monks with choice food. At the conclusion of the meal the Buddha returned thanks, and surrounded as before by four sides of flowers and accompanied by a great multitude of people shouting in exultation, proceeded to the Monastery.
So saying, he presented him with eight elephants, eight horses, eight male slaves, eight female slaves, eight magnificent sets of jewels, eight thousand pieces of money, eight women taken from the royal harem, adorned with all the
adornments, and eight choice villages. These eight-fold gifts did the king give him.
Venerable Ananda thought to himself, “Shouts of exultation and acclamation have continued all during the day since early morning. What will be the reward of the florist?” The Buddha replied “ânanda, he surrendered his life to me and rendered honour to me. Therefore, because he has immense faith in me, he will not enter a state of suffering but will receive the fruits of his good deed in the world of the gods and in the world of men. One day he will become the solitary Buddha Sumana.”
