This book presents the essential stages of St Catherine of Siennna’s human and spiritual development as exemplified in her symbolic “Tree of Virtue” with its circle of soil trunk and crown that would evolve, as the three matures, into the “Tree of the Cross.” The grief that Catherine experienced in the final days of her life, the physical suffering she endured, the sorrow she felt at having failed to achieve her life goal – to purify the church and to restore it to its pristine virtue – would bear fruit at a later date, in a new springtime of growth. she would plant the seed; God would provide the harvest.
