Your enthusiasm and willingness to persevere in the face of stark adversity has never failed to impress me. The arrogant pitfalls of the prodigal will never plague you, a boon that will see you through your future endeavours.
While I will miss you providing me the opportunity to teach others, and am saddened to know that I will not be able to complete your training, I would feel remiss in my duties as a mentor if I did not provide you some parting lesson. To that end, I have devised a ritual for you, the most important a mage of your caliber can learn. It will provide you a means for determining the cause of any calamities you face. When you again find yourself in a position of sudden catastrophe, this spell should start you down the path to correction in my absence

Your (former) teacher,
