If the boundaries of the self are defined by what we feel, then those who cannot feel even for themselves shrink within their own boundaries, while those who feel for others are enlarged, and those who feel compassion for all beings must be boundless. They are not separate, not alone, not lonely, not vulnerable in the same way as those of us who are stranded in the islands of ourselves, but they are vulnerable in others ways. Still, that sense of the dangers of feeling for others is so compelling that many withdraw, and develop elaborate stories to justify withdrawal, and then forget that they have shrunk.
