The basis of Self help in Jin Shin Jyutsu is the thumb and the fingers. Holding the thumb and the fingers every day is a good way to gently clean, harmonise and revitalise all our 144,000 energy functions. The effects over time are cumulative, so the more you hold your fingers, the quicker the effect. See these older posts for how to hold the thumb and each finger and harmonise each corresponding emotion (or ATTITUDE as we call them in Jin Shin Jyutsu):

Hold the thumb for Worry
Hold the index finger for Anxiety
Hold the middle finger for Anger
Hold the ring finger for Grief
Hold the little finger for Trying (too hard)
