Drop Unpleasant Memories Of The Past & Live In The Present Moment (theartifliving.org) How can you be happy if you’re holding onto unpleasant memories of the past? Unpleasant memories are the biggest hindrance for you to be in the present. The nature of the mind is such, it leaves all the pleasant memories and it grabs onto those few unpleasant events and chews on it. We have advanced in technology but we have not used that technology for our mind. If you are happy now, the past will not torment you and the future will take care of itself.
