The sun is at the heart of the universe. The heart chakra is at the center of your own personal universe. In the most basic sense, chakra is a spinning energy source that vibrates wave like frequencies. These energy centers are referred to as prana (the Sanskrit word for life force energy). Each chakra has different characteristics, and is associated with a specific color, aroma, gemstone, or emotion. Together, mind and body work as one. If you are feeling physical pain you must also look at your emotional well being in order to heal. Physical ailments can be linked to blockages of these spinning energies that are found throughout the body. In order for one to heal all aspects of the self must be looked at. Once we understand our own personal system, we can then achieve harmony, and peace.
Think of a chakra, and try to visualize in your mind's eye a wheel (Sanskrit for chakra) of energy. Upanishads are passed down from generation to generation. Found in the first millennium in India these Vedic doctrines and are the oldest scriptures in Hinduism. Some of the doctrines include yoga, karma, self-realization, meditation, and reincarnation). There are 200 in total.
About halfway down the list you'll find the Yoga-Kundalini Upanishad. Kundalini is Sanskrit for a coiled up snake; with the base of the serpent lying at the root chakra. At various points in history reference the coiling of the 7 chakras can be found. For instance, The Caduceus, or 'The Healing Staff'. In mythology the Greek God Hermes held the Staff. I am sure you've seen this image; two snakes that coil up to meet at a pair of wings at the top. This symbol is linked to medicine, and the image is used in present day pharmaceuticals.
Spiritually each intersection represents an endocrine (or chakra). Therefore, you could say the image is a representation of the body. Taking all this into consideration you could easily state that science, spirituality, and mythical legend are interconnected, similar to the symbol of the caduceus.
Every single space on the body represents one of the seven chakras. The goal in maintaining a healthy body, and mind is to continuously work towards building an unobstructed path, from the top of your head to the bottom. You want the life force energy of the earth to travel first through the root chakra, and the heavens to enter through the crown chakra. With a clear path the energy can flow freely to all the chakra points. Through the art of meditation we let out negativity through our breath, and inhale positive power from the universe.
Developing a keen awareness of each of the energy centers is the key to unlocking the powers to heal. Healing each energy source requires time and patience. Quieting the mind and fully immersing yourself in meditative practices takes practice. You may not reap the benefits of life force healing initially, but if you stick with it you'll notice your sense of clarity is heightened.
To begin, start with simple breathing exercises. Focus your mind on your breath, inhale and exhale. If you feel your mind wandering visualize your breath frosting glass on a cold winter day. If a thought pops into your head quickly let it go. This practice also builds your awareness bringing you into the present.
Once you have mastered quieting of the mind you can consider taking the next step, healing each chakra. There are many tools that will help you during this process. Hand positions (mudras), and chants are applied to open the chakras. Music may also be added to your practice, as it helps stimulate the vibration of each chakra. Concentrating on a color can also enhance the experience. Bringing this spiritual awakening to your inner self will nourish a healthy mind and body.
Clearing a path for your internal chi to flow gives you the power to tackle whatever problems you are facing. Chi moves through. Feng-Shui practices the same theory when it comes to space. By clearing away all the clutter you have opened the space for your Chi to flow freely. The same goes for chakras.
Now you have got the essential resources to begin your journey to open your power sources. Rest would be the door to enlightenment.
