I believe that everyone has the ability to see clairvoyantly. For some it comes much easier than for others, but I believe we all have the ability and with a little work we can use our third eye!
Activating your third eye and working with the third eye chakra allows for improvement of clairvoyant abilities. Here is an exercise I used to do and still do to gain clairvoyant skills!
In a meditative state begin to focus on your breathing and bring your attention to the area in between your eyes. Start to notice how this area is feeling and how the energy within that chakra is feeling.
Notice a white light coming down through the top of your head and moving into your forehead, notice it flowing in between your eyes and in the middle of your forehead.
Notice the energy swirl around here and become a ball in between your eyes
Notice it flow out the front and back of your head, out both sides of your third eye chakra.
With your eyes closed I want you to visualize a closed eye right in the center of your forehead in between your eyebrows. Begin to slowly open that eye and begin to blink it.
Imagine moving it up and down, left and right and blinking a few more times.
Let the energy flow out of this open eye and allow yourself to notice any images that come to mind at this time
Now you can chose to ask a question if you would like and take note of any images that come to your mind as an answer to these questions.
You can also place a clear quartz crystal on your third eye chakra during meditations for a few minutes as this will help clean and energize it.
