The most interesting thing about Ki energy is its manipulability.
Suppose there is a bunch of people, 100 of them sticking together, 50 meters away from you. If you throw a ball toward them you don't know who will be hit by the ball. But if you want to send Ki energy to a certain person in it, you can pinpoint that person.
It does not matter time and distant.
For example, my friend the Kiko master heals his patient on the phone (Distant Healig). He does not even need to talk to the patient in person. He can tell the patient's condition by simply seeing patient's name card.
You can control other's Ki energy at will. This means, at the same time, others can control YOUR Ki energy without you knowing it.
It's kind of scary, but not many people can do it in this world, so normally no need to worry about it.
However, you cannot be indifferent.
If you are Japanese living in Japan, you might have experienced this kind of thing - A stranger suddenly came to talk to you, especially in front of the station, say "I would like to pray for your happiness" and put his/her hand in front of your forehead.
You cannot be too careful in Tokyo.
According to a reliable source, those people are members of a certain religious group in Japan.
Long time ago, along with my two friends, one is a Karate master and the other is an muscular editor whose brain is also a muscle, I went to see those "pray your happiness" people in front of Shibuya Station in Tokyo, and let them do what they want. One of them came to me, saying that he pray for my happiness, and put his hand in front of my forehead. He started absorbing my Ki energy. Then I saw something in him - snakes. Snake in this case means some sort of a evil spirit. It looked like snakes. He's got those snakes, hundreds of them, in his tummy. And he fed the snakes with the Ki energy which he absorbed from me. As soon as the snakes got the Ki energy, Snake's tummies started sparkling. Then, snakes pooped. And the poops started emitting terrible, very malicious Ki energies.
Those people are raising snakes in their tummy.
For them, the snakes might be a snake god. So they appreciate the energy (poop) which the snakes give them. And I am sure they believe they are doing good for people, helping people by getting rid of "bad energies" in people. I am not blaming them. It's a freedom of belief. Good luck to them.
You know, people who are interested in this sort of things such as human energies or spiritual things are tend to be easy to be trapped. These things are farthest from scientific field, so first say, first get. You can say or whatever you want. And when it comes to a group of people, things get worse. I don't know what I try to say but there are always people who try to trap you. I leave the rest to your imagination.
Anyway, what I want to say here is, there are some people, just like me, who can control other people's Ki energy as well as his/her own Ki energy. And when you encounter those kind of people, do not jump to a wrong conclusion like "Wow, this person might be a god! Let's make an offering!". It will cost you a fortune. Just leave them alone.
By the way, even if you can control Ki energy, you cannot control things. Moving things by using preternatural power requires incredible energy. It is absolutely impossible. If you meet somebody who says that he/she can do it, better stop meeting those kinds of swindlers.
I myself can control Ki energy, can connect to the energy in universe, can absorb the earth's energy, but it does not make me a superman.
