I'm going to paraphrase Brysing here because it fits here well. He says it better tho.
If you believe in it, then it's truth for you.
Basically, if it works for you then it works for you. Why do you need validation of it? Believe in your own work. You used it so only you would know if it succeeded. What's good for goose isn't always good for the gander. I use black coffee to scry in. I didn't read it anywhere. I knew that coffee is an herb of the mind and it was black like ink, creating a nice black mirror effect. It works for me, so no matter what anyone may say, it's what I do. It may not work for you, but I don't care because it works for me. Do you see what I'm trying to say here? Believe in yourself. Observe, experiment, and use your own common sense above any other person's opinion. Consider what others say, but don't buy into it until you learn from experience (directly or indirectly), if you haven't experienced it, then you won't have a solid opinion on it yet. ;-)
