Learn the basics and cast spells. Without the basics there is nothing to accomplish. You cannot summon psi balls, you should pratice it. Hold your hands like you're holding a cup or ball and visualise energy ball in your hands. Do it perfectly and you'll succed. Concentration and will is important.
Auras can be seen through the eye. Place a friend in a white wall and watch his head. Watch closely the white energy been seen around his head. Then pratice and pratice.

In case that you are interested you can check my both videos which i made for chi balls (they are very similar to psi ones ).Both videos can be found on /from my profile page .I think it will be much more easy for you to observe someone doing the exercise and follow it rather than me writing here and you trying to read and follow .
