Yesterday I had a telephone call from Rupert (not his real name). I usually see him once a fortnight but recently he has been away suffering from bone marrow cancer. The news was good. Following courses of treatment he is now clear, although it is too early to confirm permanent recovery. Part of my pleasure is selfish. Rupert is a clinical psychologist and has a special interest in Eastern religions. He has been an invaluable contributor to the fortnightly philosophy group which I lead. And he offers his professional skills freely to members of the group.
