I wanted to go to the bank for operating my locker. I couldn't find my locker key.
Me and my wife searched the whole house for more than an hour.
Finally I sat down quiet and chanted "An inner wall of silence could be built" and just observing, without reacting to the event, without participating.
Just in ten minutes it lead me to a drawer where a leather pouch was there. I opened it and the key was there.
It was amazing.
