The third eye is more than a metaphorical or alliterative phrase for intuition. It refers to the very real anja chakra. This particular energy center stems from your pineal gland. For a more in depth summary of the pineal gland and its effects read and watch my summary here. This organ is known as the psychic gland, and from its physical placement in the center of our gray matter, the anja chakra spirals out. This chakra is the center of our intuitions. This chakra is made more powerful through repetition.
This video goes over the common traits and changes of your third eye opening. There are more than just these aspects but these are not only the most common but the most readily noticed.
Heightened Senses
All of your senses will be given a noticeable boost. It will be like living in high definition. Not only will the physical input will be more detailed, but your ability to comprehend this upgraded information will be reformed as well.
Clairvoyance
You will start to hear sounds and tasting sounds. No you are tripping, but you are now able to experience a sense and feel the other attributes tied to that particular sensation. You will see the kitchen has been cleaned and will be able to ‘hear’ your roommate’s comments on the task.
Dietary Changes Are Desired
As you can taste intention and have a heightened sense of taste and smell, the quality of you desired foods will be bettered. When I eat a burger from a fast food chain, I can ‘taste’ the impartial and loveless environment the burger was made in. I can ‘smell’ all of the corners that were cut to provide me an unnecessarily convenient and fast meal. You will be able to feel the ‘negativity’ in certain foods poorly fuel your body and weaken your spirit.
You Notice The Connections Between Life
All of these newly recognized aspects of life will fuel your raised intuition into making new connections you’ve never before realized. This high level of understanding, in both a mental and spiritual capacity, will lead to higher levels of empathy, respect and compassion.
I think looking at the moon for at least half an hour is also important.
