"Any goal or expectation you have about [yoga/meditation] is going to be a trap. It's going to trap you. You're going to be stuck with that expectation, and the flip side of it is that there is going to be disappointment."
Ok, it sounded more eloquent in my head, but so many people have said and written the same thing, in essence- expectation leads to suffering. My Providence shrink's favorite phrase used to be "find a way to let things be what they are."
That said, I have a renewed love affair with incense right now. Tarts and candles just don't produce that same, well, smokey undertone.
