Spiritual Counsel and Letters of Baron Friedrich Von Hugel.  Edited with an Introductory Essay by Douglas V. Steere.  Published by Harper & Row of New York in 1964.

 Evelyn Underhill was a distinguished mysticism author when she first met Von Hugel in 1911 and she chose him formally as her spiritual director in 1921. This relationship continued until 1925 and it profoundly influenced Underhill's writing and her own guidance of others throughout her life. Gwendolen Greene was a 'spiritual child' of Von Hugel. She remembered him from her earliest years but her formal relationship with him as her 'spiritual father' began in 1918 when she was thirty-eight and herself the mother of three children. Von Hugel, who had three daughters, took women' s intellectual development seriously.  This book contains letters to them as well as others.
