You can power your mind for psi in different ways, depending on what you hope to get from the experience. Psi abilities are broken down into two main categories: psi-gamma and psi-kappa. Psi-gamma relates to talents such as ESP and other types of cognitive abilities. Psi-kappa is psi that relates to psychic phenomena in the physical world, such as psychokinesis. Exercises that you can do to boost a specific ability in either skill set will help you to power your mind in psi on the whole.
One of the most common methods of developing a stronger ESP is to use Zener cards, which are a series of five cards marked with unique symbols. What you do with them is you guess which one you will draw, or you could try predicting the order in which you draw them. You may begin by merely guessing, but once you apply some mental focus, you can enhance your ESP and predict more correct outcomes.
Another thing to consider would be to try out exercises that raise your energy levels. With a stronger psychic energy comes a stronger psychic ability. Begin by standing with your arms by your side, the palms of your hands facing you. Place one hand over the other. Press this hand over the one you did not move, and then, maintaining this pressure, slide the hand up your arm until you reach the shoulder. At this point, turn the hand you have not moved yet so the palm faces outward. Slide your hand down your arm. When you have finished this arm, switch your arms and perform the activity again. Check to see how this exercise has affected your energy levels.
To power your mind and its psi-kappa powers, try using an energy wheel. The energy wheel is a simple machine you can easily make, and your mind can move it with you never physically touching it. There are many kits available that can help you build an energy wheel. How it works is that the fan part of the wheel balances on a very thin and lightweight pin. The lightness of this mechanism makes it easy to use for even the most novice of people looking to enhance their psychic powers. You will have to focus your mind on the pin and the fan, picturing the parts of the machine moving under the force of your mind. This exercise, and many others, are great ways to enhance your psi and to power your mind.
