I came down with cancer in 2008 and spent a lot of time in waiting rooms. I found that waiting rooms are a good place to do Jin Shin Jyutsu. I will often do a little of it while attending a meeting or listening to a lecture. It never fails to relax me. If I feel a bit restless at night while laying in bed I do it then as well. I often fall asleep that way.
There are other aspects to this technique but this is a good place to start. Jin means Knowing and Compassion. Shin means Creator. Jyutsu means art. It can be translated as, " Creator's art personally for Myself." You can hold the fingers anyway you like. I have two ways I illustrate here. Below are some explanations for what each finger can do. I start with how they effect emotions and the meridians and organs in the Chinese Medicine paradigm. More will follow later.
You can find more information about this technique at the following links,

Another very good site with a good explanation of what the finger can do follows. Read it and practice what you read. If you do, you will find treasures for you and your family and friends. You can hold other people's fingers for wonderful results. Play with this and find happiness.

Little finger above, Pretense, crying on the inside while laughing outwardly. This finger effects the heart and small intestines. I am referring to the Chinese medicine paradigm when I speak of the organs here and below.
"Fear, according to Jiromurai, is the cause of all disease. Apart from this worry, sadness, anger and pretense are also responsible for causing disease and are called attitudes. If these attitudes are corrected, healing takes place and our whole body gets harmonized physically, mentally and spiritually." (from the medindia.net)
Thumb,Worry. Worry effects the stomach and spleen. This finger may help the stomach and spleen. Remember I am speaking of the Chinese paradigm when I refer to the stomach and spleen.
