Today I learned about the Buddhist practice of "offering cakes," which convinces me even more than I am a born buddhist. "If you think nonhumans might be trying to harm you because you are indebted to them in some way, you can give them 'offering cakes.' ... It is not necessary to make a proper ritual cake. You can offer anything or just imagine that you're making some form of restitution. ...It is not the ritual that is important here, but the psychological process of saying, 'Come in, have some cake, and stop bothering me.'"
The book ("The Practice of Lojong" by Traleg Kyabgon) goes on to say that evil spirits can be seen as our inner psychological states or external being.
so by extension, it's good practice to say, "hey, depression, have some cake and quit plaguing me." offering real cake, or maybe cupcakes, of course.
