Then the store of truths (Buddha’s teachings), eighty-four thousand in the number of its gateways, is nothing but the record and diary of our own life. Everybody reads and embraces this store of truths in his own soul. Illusion occurs when we seek the Buddha, the Truth, and the Paradise outside of our own self. One who has realized this soul is called the Tathagata. When this state is once attained, (we realize that) the cosmos in ten directions is our own body, our own soul, and our manifestation, because the Tathagata is our own body and soul.
Nichiren, The Buddhist Prophet
