I keep a medical tuning fork, which has a rubber striking block, then I slowly move the forks towards the center of my forehead and just above my the center of my eyebrows. I can do this with my eyes shut and never touch my skin.
1. I feel a tingling sensation
2. I feel a tingling sensation as if someone is slowly moving their finger in a circular
or waving motion.
3. I feel a strong throbbing sensation once my third eye is fully open.
I think this could be because when this happens it like a light is on and all of my senses are super acute. I can see, heard, feel and know into the spirit real and over vast distances. This allows me to channel enties and seen them and they often will speak through my voice. I can see into peoples bodies for healing if the Angel Shonton steps into me. His voice chants beautiful colors and they penetrate the body for healing or removing unwanted spirits.
Your third eye is a very useful part of your body to help you advance and broaden you abilites. It is very important to not get discouraged because one must keep themselves as clear as possible. I increase my vision and length of time and scope by placing a quartz flat faceted crystal about 1/4 inch thick and 1 1/2 inch in diamete on my third eye after I have used the fork and meditated into a theta state of trance to become even more removed from the distractions. I use the Angel tuning forks to increase along with reiki energy touches to the back of my head, forehead and around the ears for clairaudience and on my heart for feeling and sensing. I also like to turn on all the chakras on my body to their highest frequency and speed of spinning of the light energys and I call the white light down through the top of my head. This fully illuminates everything to me to the point of a very bright looking flourescent light, then as Angels or Ascended Masters enter the room they look like spheres then bloom into their shape. This varies depending on my energy. Sometimes I see great vivid detail and at other times I connect with their energy and they remain as an energy form presence.
I hope this will give you some great sense of excitement about what we are all capable of doing. It requires work, however; all this that are worth have are well worth the effort. I am eager to answer and ask the sources that work with me for answers that could help you achieve your efforts. I have spoken with many that still have a problem with their third eye opening. Remember, do not expect the results that I have. Work at first to gain just a feeling at the point of the third eye.
One other thing, I have found looking at certain shapes and objects will automagically open my 3rd Eye. A pyramid, and inverted cresent moon with a solid dot suspended in the middle. Speaking the word 3rd Eye and Seeing the Words 3rd Eye.
With Love, Light and Enlightenment.
