Also, Dr. Peter's a great one for whistling chants, or someone may go around humming. It's probably one of the things we do most specifically. We have pictures and sayings at our desks, and those help me specifically. Also, chanting mentally helps a lot, and reminding myself mentally what I'm there for. Or looking at Yogananda's picture, or pictures of other saints.
Different people have their own ways of refocusing.
Another thing I do is pray for the clinic, pray for us to learn our lessons there, and pray that God will be with us.
