We spend a lot of time looking at things. We look at objects, rather than the space around them. We look for answers, rather than looking for the right questions. Begin looking at the space surrounding things, and for questions you have not yet thought to ask. It is in the space between objects, between breaths, between thoughts that we can perceive subtler energies.
Psychic ability is a skill of the mind and imagination.
Imagination does not mean it is not real. Begin by focusing on a rock, or other object of the mineral kingdom. It can be a mountain, a crystal, a pebble, a boulder. Focus on this object for a few moments, then imagine your head expanding, opening, and becoming a part of that object. Imagine it in great detail.
