That's easy.   I don't.   God does, and it's so simple.   One has only to understand:  (a)  how "The Universe" works,  and  (b)  to invoke the laws of God.   I'll share a parable with you which will make this clear.

Forty-Nine E-mail Viruses

Twice upon a time. . .   I say twice, because in this story, "once upon a time" just isn't quite appropriate.   At any rate, twice upon a time, there was a man who sent forty-nine computer viruses to the same email address while believing that he was doing God's work.   But guess what happened.   The wise person who received the infected e-mails  simply followed the maxim given to humanity from The Ultimate-Source-of-All-That-Is (which we call Creator/God).  That maxim says:   "Forgive them Father, they know not what they do."  

The Angel of  Light      The Angel of  Light     ... 

However, before he moved on, that wise person also invoked the   Return to Sender  blessings of The Source of All  (that we call God) and said:

 " Father, send an Angel of Light to the person who sent those e-mail viruses to me.   Direct that angel to shine the Light of Your truth into his face.   Direct Your Light onto him and shine it so brightly that his fellow peddlers of harm-to-others see the light and think that he has become a traitor to their cause."   See the Section below for the complete invocation.

And low and behold, it was only a matter of time before the laws of God began to take effect, and the maxims began to come home to roost:

"As you sew, so shall you reap. "  

"What goes around comes around."   

"Whatever you do onto others, you also do onto your self."

And no matter what that peddler-of-harm did,  every single bit of what he put out started, step by step, to come back to him, and it soon started coming back so strong and so hard that he realized that he had only two options:   

1)  He could either regret harming others, pray for forgiveness, and change his ways, or 

2)  His fellow peddlers-of-harm would quickly see that something was wrong with him.  They would see him as a traitor to their cause and deal with him according to their own laws.

God and the laws of the Universe are so powerful that  no human being has ever escaped the laws. '   So, whenever that poor fool who sent the forty-nine viruses looked into the mirror and looked very closely, he  saw that light from God's Angel of Truth shining onto him from behind his left shoulder.    He was fearful enough to also  look over his right shoulder, because he knew his compatriots (his partners in causing harm) were also watching him.   But, he had one small problem -- he was not wise.

God's laws are always fulfilled!

I'll simply leave it to your imagination to figure out what happened to him.   All I'll tell you is,  "Be very thankful that you are not him!"

Most of those who would cause harm to others have a very limited view of reality.   Commonly,  these people have been strongly indoctrinated into a particular religion and they have never questioned the truth or the reality of what they believe.   They believe simply because someone else told them what to believe.   They live inside an invisible prison ^'  called a  Belief Box. '  These people confuse reality with beliefs about reality. ^' 

If you choose to response directly back to those who have directed harm at you or at others, a word of caution is in order.   Do not  intentionally harm these people.   It's not necessary, and you could  also end up  harming yourself.    There is a very effective and foolproof alternative.  See the section below titled:  Undeliverable -- Return to Sender.

Because The Law of Cause and Effect '  functions in both the visible and the invisible portion of the universe,  connecting an effect with its cause is often very difficult.   The perpetrators-of-harm usually are functioning out of  (and at the effect of)  a very limited belief system, and thus, they are almost always unaware of the long-term consequences of their actions.

One of our main, personal goals is to stop others from directing their negative behavior at us.   In order to accomplish this, we must show those-who-would-harm-us  a clear connection between cause and effect.   This requires that the-perpetrators-of-harm become aware of the personal consequences that come back to them as a result of their actions.

To accomplish this using the Return to Sender  Invocation,  another piece had to be added.   We had to overcome the problem that many people do not believe the Universal Laws are real.   In order do this, we realized that we must speak in a language that the uninformed will understand.

We prayed and asked Creator for a way to inform these people that the Universal Laws are real and that everyone is at the effect of  the laws. '    The response we got back was:  "Give them a  Buddha Gift. '       Use embarrassment, ridicule, and minor annoyances, things that will serve to awaken them without causing any real or permanent damage to anything or anybody."

A simple way to do this is to use the  "Return to Sender"  Invocation   described in the section below.   Send them an angel of light, not only to shine the light of truth onto them, but also to give them a very itchy butt, a butt so itchy that they can't sit down  for a week.   Invoke the itch onto them and onto their entire family.

So we offer this to those of you who would causes us harm:  The Laws of the Universe are real, and you are about to experience that truth, beginning with a big-time, itchy butt.   So if you have another forty-nine e-mail viruses to send, we suggest that you (to say this politely)   "sit on them!"

Integration Time:

Visualize that your invocation is created in the non-physical realms and now that it has been created, it's also a physical reality.   Sit silently for a moment and take a deep breath.   This keeps the mind clear and allows time for your directive to become strong and clear within you inner self.   It's like hitting a home run and stopping for a moment to watch the ball sail over the fence.   In your mind, see your invocation as real and as having arrived at its destination.   See, hear, and feel your declaration as accomplished.

Then Fill Yourself with Light:

Speak out loud the following invocation.
