From Buddhism's Sacred Scripture: The Sutra of the Lotus of the Wonderful Dharma, Chapter 3, Part 1 of 8

WHEN I HEARD THE SOUND OF THIS DHARMA (true teaching), I gained what I had never had before. My mind was filled with great joy, I was released from all bonds of the net of doubt. From past times I have received the Buddha's teachings and have not been denied the Great Vehicle. The Buddha's sound is very rarely heard, but it can free living beings from distress. Already I have put an end to outflows (earthly desires), and hearing this, am freed from care and distress. I lived in the mountain valleys or under the forest trees, sometimes sitting, sometimes walking around, and constantly I thought of this matter-how severely I taxed myself!
