Consider the idea that your hair is on your head for reasons other than vanity.
Humans are the only creatures who grow longer hair on their head as they mature into adulthood. Left uncut, your hair will grow to a particular length and then stop all by itself at the correct length for you. From a yogic perspective, hair is an amazing gift of nature that can actually help raise the Kundalini energy (creative life force), which increases vitality, intuition, and tranquility.
The bones in the forehead are porous and function to transmit light to the pineal gland, which affects brain activity, as well as thyroid and sexual hormones. Because of this flow of energy, primitive people kept their hair long, avoiding bangs to keep their forehead and pineal gland exposed. For example, When Genghis Khan conquered China, he considered the Chinese to be a very wise, intelligent people who would not allow themselves to be subjugated. He therefore required all women in the country to cut their hair and wear bangs, because he knew this would serve to keep them timid and more easily controlled. As whole tribes or societies were conquered, cut hair became so prevalent that the importance of hair was lost after a few generations, and hairstyles and fashion grew to be the focus.
In addition, some believe that hairs are the antennas that gather and channel the sun energy or prana to the frontal lobes, the part of the brain you use for meditation and visualization. These antennas act as conduits to bring you greater quantities of subtle, cosmic energy. Accordingly, it takes approximately three years from the last time your hair was cut for new antennas to form at the tips of the hair.
There are ways to increase the Kundalini energy of your hair no matter what the length. During the day, the hair absorbs solar energy, but at night it absorbs lunar energy. Keeping the hair up during the day and down at night aids in this process. Braiding your hair at night will help your electromagnetic field balance out from the day. Keeping your hair coiled on your crown and protected with a head covering during the day will help your antennas heal. If you have long hair, see if your experience is different when it is clean and coiled at your crown, or down and loose. When you put your hair up wet, it will tend to shrink and tighten a bit and even break as it dries. A better idea is to occasionally take the time to sit in the sun and allow your clean, wet hair to dry naturally and absorb some extra vitamin D. Yogis and colorists recommend shampooing the hair every 72 hours or so. It can also be beneficial to wash your hair after being upset to help process emotions.
Do not fear if your hair is thinning or graying, as these are normal in the aging process. If your hair is thinning you can make up for the loss in energy absorption by increasing the amount of meditation you partake in. If you are finding some silver strands in your hair, be aware that the silver or white color increases the vitamins and energy flow to compensate for aging.
Tagore the great poet who found god within himself has said, “When I realized the Oneness of all, I threw my shaving kit into the ocean. I gave up my ego and surrendered to nature. I wanted to live in the form that my Creator has given me.”
These concepts are merely something interesting to consider when you think about your physical connection to the energy fields that surround all of us, and tie us together. In modern times its up to each of us as individuals to determine the correct length and style to aid us in our ascension. Whether your hair is floor length, non-existent or anywhere in between, meditation and conscious living will bring about the same developments in Kundalini energy as having uncut hair.
