Venerable Cassiani the Hymnographer - Troparion & Kontakion

Troparion — Tone 4

In you, O Mother, was preserved with exactness what was according to the image; / for you took up the Cross and followed Christ. / By so doing, you taught us to disregard the flesh, for it passes away; / but to care for the soul, since it is immortal. / Therefore, O Venerable Cassianḗ, your spirit rejoices with the Angels.
