Memory is really useful - sometimes - like when you need to remember where your car's parked, or where the grocery store is.... but often, memories are inaccurate recollections of events or people that can just cause distress and even persecution in the present moment. Add in the possibility of re-incarnation, and the option of memories from dozens of previous lives, and you a potential memory-mine-field....be wary of memories - if they're not serving you well, look to get on with your life in the present rather than dwelling on the past!
