There are not many great Buddhist writers. This is not an accident; good writing is just not an aspiration for most Buddhist teachers. The Dharma is shared in words, practice, shared experience, and community. Writing carries with it the necessity of saying something new and valuable to as many people as possible, while the domain of a good teacher is to impart what is old and worn and true in the way which speaks to the heart of the individual whom most needs to hear it.
That is why I am fascinated by the curious case of Master Yin Guang (印光), a pre-Civil War Chinese Pure Land master. Master Yin Guang lived most of his life in seclusion on the Buddhistically sacred Mount Putuo off the coast of southern China. He did not perform lavish ceremonies or amass skads of lay and monastic disciples. But he did write.
He wrote letters.
