Dear Reikilady,
There was a time seemingly not long ago when I thought this was a silly approach. When I found that it works my ego judgement on this lost sway:
Ask the book where it is. Outloud ask : "where are you little blue book"? And then let it go to the back of your mind and endevot to be open to when the clue or outright answer comes.
Namaste,
Michael
