The reasons are somewhat similar, then. At home, each of the cultivation sects have their own traditions which are only passed down to members of the sect. Certain skills and abilities are dangerous in the hands of those who would misuse them, so we take care to ensure, to the best of our ability, that they are only given to those who will use them for the betterment of all. Things are different here because there are no longer any in Vallo besides myself who would be able to make use of the most powerful cultivation techniques; they are particular to our sort of magic, so even if you were to read of the Song of Strife, you would not be able to recreate it and use it to drive a man to madness.
Protecting garments and tables from paint and soy sauce, however, is a technique I am willing to share with others. :) I do not know if you will be able to make this magic work with yours, but I am glad to give you what you would need to try.
