There is a story about a cousin of the Buddha whose name was Badhiya. He was governor of a province in the kingdom of Shakya, in present-day India. One day a number of his friends who were monks and students of the Buddha came to him and invited him to join their community. He hesitated. As a governor, he had at his command many soldiers, a lot of money, and a very powerful position. But finally his friends persuaded him. He left it all behind and came empty-handed into the forest, where he was ordained by the Buddha as a monk. He didn't have a fancy house to live in anymore. He only had three robes, one bowl, and a sitting mat.
One night Badhiya was meditating at the foot of a tree. Suddenly, he uttered the words, 'Oh my happiness, oh my happiness. It happened that another monk was sitting nearby. The other monk thought that Badhiya regretted having abandoned his position as governor. So in the early morning l that monk went to the Buddha and reported to him. 'Dear teacher, late last night I was sitting in meditation. Suddenly I heard the monk Badhiya exclaiming, "Oh my happiness, oh my happiness." I think he has some problem.'
The Buddha sent his attendant to invite Badhiya to come. In front of a group of monks the Buddha said, 'Badhiya, is it true that last night during sitting meditation you pronounced two times the sentence, "Oh my happiness, oh my happiness"?" Badhiya said, 'Yes, noble teacher, I did pronounce that sentence twice.
'Could you explain to us why you have pronounced these three words during the night?' the Buddha asked.
Badhiya said, 'Dear teacher, when I was a governor my palace was guarded by hundreds of soldiers. But I was still very afraid. I was afraid robbers would come and kill me or at least take away all my valuables. So day and night I lived in fear. But last night I realized that now I have nothing to lose. I was sitting out in the forest at the foot of a tree, and never in my life have I felt so safe. Nobody wants to kill me anymore because I have no power, no wealth, and no jewels for anyone to take. I have nothing. Yet I finally have everything. I am touching such a great happiness and freedom. That is why I have pronounced the words, "Oh my happiness, oh my happiness." If I have disturbed someone, I am sorry.
