Try relaxing, taking a few deep breaths, and holding the tips of two fingers together. Looking past them, let your eyes go out of focus slightly. The idea is to look at the space around what you are trying to see the aura of. Slowly pull your fingers apart and there should be a wavy line or some light or some sort of indication that something is there between your fingertips. Mood, lighting, and background can be very helpful. Repeating the experience gets easier after you have done it a few times. With some practice, you will find that the combination of mood, lighting, and background will cause you to start to see auras around people when you aren't trying to. Of course, the more you work on it the more this will happen.
