" The Buddha, in recovering his capacity for nonsensual joy, learned that this joy was limitless. He found that if he got himself out of the way, his joy completely suffused his mindful awareness. This gave him the confidence, the stability, the trust, and the means to see clearly whatever presented itself to his mind. In the curious bifurcation of consciousness that meditation develops, where we can be both observer and that which is being observed, the quality of joy that he recovered did not remain an internal object. It was not only a memory or merely a feeling to be observed; it was also a quality of mind that could accompany every moment of mindfulness. The more he accepted the presence of this feeling and the more it toggled between being object and subject, the closer the Buddha came to understanding his true nature. "
