As one grows older, things are conditioned by parents, teachers, managers, peers, and everyone else. The third eye gets covered with layer upon layer of illusion and confusion, until your third eye gets closed and your inner witness is in the dark, leaving you empty to the world's wonders and the wisdom that your mystic sight could have delivered.
An example of how conditioning can close the third eye and forever affect life and perception of the world is a mother holding a teddy bear out to a child and saying, "Look at the little bear, how soft he is!" The child begins to recognize the shape and associate it with the name "teddy bear," and he is introduced to concepts like color, size, texture, etc.
Thus, begins the child's habit of replacing his own perceptions of the world with a process of labeling, reacting emotionally and physically to external suggestions, and mentally processing reactions and experiences according to how others perceive things.
As he grows, the child gets farther and farther away from living life as it happens in the moment - the pure, unfiltered experience with which he was born. And upon reaching adulthood and beyond, the process of analyzing, comparing, judging, and discussing things with others results in being even less connected to the "Now".
When you put shutters on a window, very little light comes through and the people inside the shuttered room can only imagine what might be outside, on the other side of the shuttered window. So they are in the dark about what life is really about outside the shutters.
In the same way that it is impossible to describe an orange adequately to someone who has not ever seen the color orange and has never tasted citrus, a person cannot fully understand seeing with the third eye from simply reading about it or hearing someone else describe it.
But now, as an adult, you have the maturity to appreciate those wonders and understand them.
Practicing Third Eye Meditation
✿ Instruct your mind to stop its internal chattering; command your emotions to be silent and serene, and focus your attention away from any physical discomfort or pain, and instead pay attention to the sound of your breathing, coming in and going out, cleansing you and filling you with peace.
✿ During your meditation - during any meditation - never chastise yourself for anything. For instance, if you realize that your focus is drifting away from the meditation, accept it without being critical of yourself, and continue with your meditation.
✿ Close your eyes and focus on the area right between your eyebrows. Maintain your focus and attention on that spot, and before long a point of light will appear inside your inner vision field.
✿ Keep focusing on that inner light. Some people may find it useful to raise their eyeballs - continuing to keep the eyes closed - upward at an angle of about 25 degrees. For others, simply directing their focus upward is easier and not as distracting.
✿ After experimenting and discovering which approach works best for you, use that way exclusively. For absolute beginners, it may be beneficial to put your thumb on the outside edge of one eye, and put your middle finger at the outside edge of the other eye, giving yourself a point to focus your attention on.
✿ As you begin to perceive the truth and reality that is the Now, you will realize that you have been deluded by outside influences into thinking that you are a separate part of the universe.
Third eye experiences allow you to realize that what you have always considered to be "real life" has actually been a performance being played out on a stage for you.
Because this "real life" is just a singular story, and your real life is a partnership with the universe, anxieties and fears with which you have been grappling will be replaced with joy and bliss that is experienced by merging effortlessly with all of creation, and in the process, finding true self that you were born with but lost somewhere along the way.
