Excellent replies all. Mine is perhaps not so excellent but I will offer it for a person like me. Not to say the initial poster is like me, but a suggestion it may be for that unlikely event...
or someone who reads this who is like me..
I can simply find noone who has harmed me who is the person who has harmed me. Changes have occured and that person no longer exists.
My arrows aim of revenge or retribution will be far off its mark. Striking a innocent it will. The person I strike has not performed the deed.
As all is circumstantial in origin, a being that I perceive to be individual that i perceive as individual harming me is not such.
A composite only they are and as so am I neither may in fact harm either. I may as well blame a tree whose limb falls on me for growing a limb, that limb falling off in storm and hitting me on the head. Quite unfortunate but I cannot blame the tree, nor limb nor storm. I may perhaps learn not to be under a tree with a weak limb in a storm for future use. The tree has done what circumstances dictate...nothing more nor less.
I can find noone not like me. As I am composite in nature I can find nothing that is not fashioned thusly. So I cannot imagine or fathom a thing composite in nature and form having differing composite performing or engageing not in any concievable fashion.
As I see myself thusly I can envision doing anything or nothing in a unfathomable amount of concievable circumstances. To include produceing the circumstance of harm upon another that I am presently engaged in.
So as I always seek to cognicize be aware, understand and continue to be so doing, I cannot rationally wish another not be doing so.
So as seeking to understand is a form of compassion(compassion always is elicited by understanding)...I cannot help feeling compassion for another, as all are exactly like me in this fashion.
As I feel compassion thusly for myself I must feel compassion thusly for all.
So it simply cannot be that I do not feel compassion. Seek to avert harm and not stand under weak limbs in storms...sure I do that constantly.
Hate the tree limb storm or myself for standing under the tree in such a circumstance, stupidly....no. That would be quite absurd.
We create our reality what presents to us through our stupidity, our ignorant assumptions of things and thusly it is to be expected that we will act stupidly and have stupid things happen to us.
So I can only work to avert the heart of the matter...stupidity ignorance. So I will see all storms weak limbs and such things coming...and be not harmed.
Death is the ultimate weak limb bound to fall. I cannot hate death, quite silly that would be. The greatest abuse, someone to kill me.....I would certainly rush from that limb falling. But hate the limb....silly. I am the creator of that circumstance not another. So none may kill me....only me. None may harm me, only me.
Again not to confuse that with not rushing away from falling limbs in storms...certainly I must do that. I don't particularly feel compassionate towards those limbs...they don't care, I feel about the same to all trees. I can't hate or work to harm them....it would be quite silly. When the storm is over I may work to cut trees weak branches, if they are on my property and I have the tools at hand. If not not. There are billions of trees with weak limbs and billions of storms and places to stand under such things I don't make a big deal about one personal tree whose limb may fall on me. If I want to be hit on the head I will find one. If not I will avoid such things. I expect the limb of death to fall on me....my birth demands it. Silly me.
I wish all trees well...but they do not care. To do otherwise....I could not do.
I hate to be silly
So hating to be silly is how I have compassion.
So....that's my trick to add to the excellent comments offered. For a person like me.
A comical aside but literal fact, and hence the reference....I live adjacent to a national forest, am sitting at a desk looking at a large pine tree take daily walks through the forest and am in fact at this moment nursing a bump on my head from a tree limb(though not a falling one). Hence my affinity for trees and my circumstantial response to this question.
Thoughts to harm another things places or objects....thoughts are just thoughts they come and go without substance. Who cares what I think...I pay it no mind. Circumstantial they are as well. Good or bad ones...I can't claim a one to be mine. Feelings about the same. Moods negative or positive. Of no concern.
Intent.....I decide intent. And no intention of harm can occur.....it is simply silly to do so.
Seems such to me....internal dialogue.....a stream of circumstance/energy only, what humans do. Intention.....a action, a thing performed. Quite dissimiliar to my view. So prayer doesn't get employed by me, excepting as necessitated by oath or vow. And this engaged for another, not me.
So quite likely few are like me, nor desire such. I am not selling this thing of me. Just that some may be like me, and engage such things in this fashion.
Truth be told I added the last part as context for clarification.
