White Howlite – It is an extremely calming stone.  
 
Psychologically - Howlite teaches patience and helps to eliminate rage & uncontrolled anger.  While wearing it, it will absorb your own anger and any that is directed toward you. It also supports overcoming a tendency of being critical and selfish while strengthening positive traits.  It can calm turbulent emotions, especially those that have past life causes.  It helps to release the strings that are tying the old emotions to present life triggers.
