If you want to forget something or someone, never hate it, or never hate him/her. Everything and everyone that you hate is engraved upon your heart; if you want to let go of something, if you want to forget, you cannot hate.
The Buddhists say if you meet somebody and your heart pounds, your hands shake, your knees go weak, that’s not the one. When you meet your ‘soul mate’ you’ll feel calm. No anxiety, no agitation
