Tomorrow ( February 10th) in my liturgical calendar is the commenoration of St. Scholastica, the sister, some say twin, of St. Benedict, the founder of our Order. She was also a great monastic in her own right. In our tradition we have a number of "partnered" saints of opposite sex, many of whom were monastics: St. Francis of Assisi & St. Clare; St. Augustine & St. Monica (his mother); St. Brendan the Navigator & St. Briga; St. Basil the Great & St. Macrina. Some of these "partnerships" were brothers and sisters, Parent and child, or close friends. The tradtion is that they supported one another in their spiritual and monastic pursuits.
Are there any examples of such relationships in the Zen Tradition?
