Steps for Unblocking Your Third Eyee
If there are ways to develop your psychic ability, there are also ways to open your third eye. Here is a simple exercise with 7 easy steps for you to start with.
1. Find a quiet location where you will not be disturbed. Choose a dimly-lit place, or soften the lighting if you are in a well-lit room.
2. Start relaxing your body by sitting down on a chair or on the floor. Feel your shoulders relaxing with your hands resting on your lap or your knees. Keep your back straight, but not stiff. Align your neck to your back so that you are looking straight ahead.
3. When you are comfortable in your sitting position, focus now on your breathing. Slowly inhale, and then slowly exhale, releasing all the air from within you. Spend a slightly longer time exhaling than you did inhaling.
4. If you observe that your breathing has already stabilized, you can proceed with timing your meditation. Set an alarm for 15 minutes. This may be increased through time by 5 minutes, though you can do so when you have eased into this exercise. For now, set your alarm for 15 minutes and place it within your reach.
5. After placing the alarm within your reach, place your hands back on your lap or knees and gently close your eyes. As you inhale slowly, shift your focus to where your third eye is - the point above the middle of your brows. Continue breathing with your focus on your third eye.
6. As you continue to slowly breathe in and out, maintain your focus on your third eye. Keep focused even as you feel your body relaxing more and more. You may feel a slight tingling sensation on the area of your third eye; that is perfectly fine.
7. Do not open your eyes instantly when the alarm goes off. Reach out to turn off the sound while keeping your eyes closed. You can only open them when you feel that you are ready to do so.
Do this daily, around the same time each day. The results may not be instant - you wont immediately have an exceptional psychic ability or a fully open third eye - but know that as you do this, you are sharpening your psychic ability and developing a deeper awareness of and connection with your third eye.
With regular practice and perseverance, you will soon experience the remarkable benefits of having an open third eye and of seeing with it. This will also have a huge impact on the development of psychic ability. You will be able to do and achieve more things when it comes to using your psychic skills.
So start incorporating this meditation into your daily routine. Doing so will surely and effectively enhance your psychic ability and open your third eye.
