Gertrude the Great's "elder sister" in consecrated life—who was among her teachers as well as a guide and friend—is commemorated among Benedictines as one of the particular saints venerated in the order (I may be wrong, but this seems similar to the status of "blessed" in the Roman church). Mechtilde ("Matilda") was also known for her mystical closeness to the Heart of Jesus.
"O good Jesus, I love You, and whatever is not in me, I beg of You to offer to the Father in its stead the love of Your own Heart.... I offer You, therefore, this love, in order to supply thereby for all that is wanting in me" (Saint Mechtilde von Hackeborn, c. 1290; feast day November 19).
