The heart sutra is one of Buddhism sutra. We Japanese call it 'Hannya Shingyo(般若心経)'. I didn't know much about it, but Knowing more, it shows me more interesting aspect. I have wanted to know and thought what is I have to do, what I should be, what is the purpose of life, what makes us feel happy, etc. Furthermore I these days wanna know old good things like Analects of Confucios because of back action searching for new and Western things. Sometimes I feel I have no basis which I could stand on.
