The ability to influence the motion of groups of atoms in their liquid state. Unlike pyrokinesis, nothing is created. The talent merely allows the psionic to influence the motion of liquids (but cannot control the motion of the atoms/molecules to heat up or cool down the liquid). Requires line of sight to manipulate an object.
The exercise to learn this technique is very similar to that of regular PK abilities. I am speaking of the old cork in water exercise, only this time we are not trying to move the cork, we are trying to move the water in which it sits. The only purpose of the cork is to indicate movement in the water.
OK, so you may say "isn't this just PK with water?". Well it can be. But if you want it to be true hydrokinesis, you must establish a real connection with water, and not just the physical substance, but the Element itself. If your natural Element is water then you will probably find this easier than most because you already have an advantage.
Spend time in meditation and contemplation, thinking of nothing but the properties, associations, and real feel of water. Totally surround and submerge yourself in it if need be. Take it into your being. Become a master of water.
Once you fell you are ready to try true hydrokinesis, do the following: Take a medium - large bowl and fill it with water. If the bowl is glass this may be easer because you can see all of the water within. Now place a cork or something similar which floats in the bowl and wait for it to settle. Once it has settled, close your eyes. Sense the water in front of you, feel its energy and merge it with yours. See in your mind's eye the link between you and the liquid. Feel its smoothness, its cool healing properties.
Now try to mimic those feelings within your own energies. You and water are one and the same.Then Open your eyes.
Just as you have control over your own energies, so too do you have control over water.
Look at the substence within the bowl. You are a part of it, and it is a part of you. Keeping in mind your connection with it, will the water to move, just as you would with your own energy.
Make it start to swirl in the bowl, always getting stronger, always gaining speed. It is you.
Continue to do this until you feel you have succeded or are in need of rest. Don't over do it on the first few tries.
Have a mental rest, you need it!
