When a person lives in the past, what they’re trying to do is change the unchangeable. The time spent doing this is not in one’s best interest and it’s one’s own mind that creates this nonsense.
For the one who doesn’t know their own mind, they know not what they do. It is imperative to know your own mind if you ever want to break free of its grasp, and don’t think for a minute that you aren’t in its grasp; just look how you always want something to be different that can’t really be changed. Every moment spent in the past is time wasted on trying to change the unchangeable. No one would purposely waste time in a life that is limited in the amount of time one is alive, but it is done all the time. So if this isn’t done on purpose, why does it occur?
All of life is precious, so it’s not that any moment of life is truly wasted, but the more time that’s spent trying to change the changeable, the less time one lives in the reality of what is. And it’s only in the way one’s own mind has been developed that makes one think that the unchangeable can be changed; look and see this for yourself. This is so subtle that the person who doesn’t know their own mind will not truly know what they do.
You have the capability to be mindful of every moment of everyday, but this
takes much discipline. Either one will control their mind or be controlled by it, but understand when you’re controlled by it, you don’t really know what you’re doing. Take heed is this, for the Conditioned Mind is subtle and if one doesn’t learn to stop trying to change the unchangeable, the moments spent doing this will continue to make one live a life that isn’t reaching its fullest potential because it’s being lived in moments that no longer exist.
