Lets start with the morals of surrogating
Do you have the right to surrogate someone else without asking?
A little about "interfering" in someone elses life:
The Bob process has a major safety statement hard coded into it that will determin 100% if the Bob process will be accepted by the users brain.
The Statement: "I agree to command my subconscious that... this will be done only if it's within my highest good and growth towards self empowerment and self love."

I added this as I watched a documentary years before I created Bob, but it stuck in my mind, you can read it XXX ADD LINK here. About a lady who had her head run over by a truck yet after several years and dozens of super painful head surgeries to put her skull back together she considered the accident to be the "best thing that ever happened to her". And she explains why.
I thought "wow". What if people need that anger, that depression etc, then I thought the higher aspect of them would know, so I'll give the final decision to their higher aspect.

So maybe sometimes Bob wont work because the higher self refuses Bob. BUT I've never seen that happen in 30+ years of treating clients one on one. The only times I've seen Bob not work was when 2 clients were over 70 years old. I assume it's because of losing neuroplasticity as we age. ie the ability to grow new and change existing brain neurons. Surrogating another person is something I learned in a particular style of kinesiology aka muscle testing, more details here .
Where the surrogate process is often used when testing a baby or a quadriplegic etc. Even a youngish child that isn't focused enough to maintain a firm muscle for the test. They can drop focus and their arm responds weak but perhaps they just relaxed their arm and your testing for allergies so accuracy is important. In these sort of cases the kinesiologist will test the child via a muscle test on the parent of the child. A surrogate.

What you will be doing via the "flick" test or muscle test is testing if the person that you're surrogating brain agrees with the Bob template stored in your energy field. I say "flick" test as it's more descriptive than muscle test. Also far more discrete. Use any hand, for the majority of people this is easy to do with either hand. Can you flick someones ear with either hand? yes.

Surrogate Process
1. Clear intent. Example "I intend to help my friend clear any and all negative emotion she feels right now"
Or,"I intend to make my friend feel better more often".
Can be said just in your mind, doesn't need to be out loud.

Then immediately do the below -

2. Do "Flick" Position Hold pressure between thumb and index finger, or middle finger then relax and then repeat. Relaxing the fingers (But maintain flick position) between 1st and 2nd flick. Re:Strong, relax, strong, done.

Done.

The most important aspect of surrogating someone is to have clear and defined intention. The person that tested this new version of Bob with the surrogate function for me for the first time tried it on her ex partner without telling him, who was talking in a negative frame of mind and the surrogate process didn't work, the person just kept talking with the same attitude. Later testing it, it did work fine several times and since then many have tested with good results.
She herself said that the first time she may have had mixed intentions, she wanted to test Bob, wanted the other person to change, wanted to help me by getting a positive result,  etc.
If you're doing a surrogate session on someone and you haven't told them then your intention must be clean ie, you're doing it for them, not for some alternative reason like, to stop them winging about their ex. It must be along the lines of "I intend to help this person feel happier". NOT to make you feel happier.

I like the surrogate process being included in Bob because Bob will spread wider and faster if people start doing it. But, more so for lets say a scenario with domestic violence, if a women does Bob via the video, or someone surragating her does Bob on her, she can then surrogate her partner and very likely remove the anger. She can do it while he sleeps or at anytime and can repeat trying till it works, if after it succeeds it wears off as her husband recreates the anger patterns via his thoughts and she can repeat Bob whenever required, perhaps it calms him down enough for it to be safe for her to leave him.
