That word is one of my favourites.
Because most of what we think on the surface appears true and valid. But after you examine it, ask yourself why, and if things actually are the way they seem, you’ll often find a completely different answer. And you can get much deeper in understanding what’s going on, yourself, what you want, and what’s really important to you.
(But only IF you keep it to yourself):
That’s annoying, but if you do keep it to yourself, and examine everything you do, what actually matters and why, it has great power.
