Above all, I instruct you to keep the holy faith unblemished and untouched by any slander, as we received it from the holy fathers, without mixing it with foreign and different teachings. Stand firm, hold on to the traditions you have heard and seen in me. Branch out neither to the right, nor to the left, but go along the royal way. Keep yourselves from worldly passions and always remember why it is you have left the world, and why it is you have despised the world and what is in it.
From the Spiritual Testament of Saint John of Rila (March 25, 941)
