A well known remedy in astrological circles towards building and strengthening your willpower and at the same time keeping your mind peaceful and strong is to wear silver jewellery! You can wear a Kara (bracelet) in your right hand or even better is to wear a silver ring that is without any joint or a silver chain with a small silver ball.
Whatever it is that you wear please ensure that it is completely without any joint and physically touches the skin of your body. Yet another well known remedy is to drink water in a silver glass. This will help you greatly towards keeping your cool and staying in control of your emotions.
