The pineal gland, which is sometimes referred to as the third eye, is a small endocrine gland about the size of a raisin. The pineal gland has important physical functions. It is also considered by many to be the most mysterious part of the human body. Some people believe that the pineal gland links the physical body with the spiritual world.
The pineal gland is a reddish-grey colour. It is located in the geometrical centre of the brain, right between the left and right hemispheres. The pineal gland is the only part of the brain that is not cut off from the rest of the body by the blood-brain barrier. The pineal gland looks similar to a tiny pine cone and its main function is to produce the hormone melatonin. Melatonin is an antioxidant hormone which neutralises the damaging impact of free radicals. Melatonin also regulates the biological rhythms of the body. The sleep/wake pattern, for example, is regulated by the hormone melatonin. The pineal gland also secretes an antioxidant compound called pinolene.
Fluoride, which is found in tap water and toothpaste, impacts the pineal gland once it is introduced to the human body. Consuming fluoride leads to the calcification of the pineal gland. In other words fluoride hardens both the soft and hard tissue of the pineal gland. This impedes the production of melatonin and interferes with the biological rhythms of the body. Hence someone whose pineal gland has calcified may have problems dropping off to sleep at night. Some conspiracy theorists believe that the powers that be put fluoride in drinking water on purpose, with the aim of blocking the psychic awareness of the populace.
The pineal gland has been linked to the metaphysical for thousands of years. During the course of history, many religious and spiritual leaders have endeavored to reach higher consciousness by awakening the pineal gland. Some people believe that the pineal gland is a channel that links the physical body to the higher self. The pineal gland is also known as the sixth chakra. Opening or activating the pineal gland is said to lead to greater psychic awareness, and knowledge of the divine self. It has even been suggested that opening the pineal gland allows the individual to see beyond space-time into time-space. People who wish to activate their pineal gland generally attempt to do so via meditation or visualization yoga.
