Chakras and Energy
As stated earlier, chakras are based on the concept of the wheel. That is because the chakra is a core of energy that then radiates out to the other parts of the body. Picture a magnetic field emanating from its source. When there is tension or pain in a particular part of your spirit or consciousness, it will affect your energy flow and will be reflected by pain in the areas of your corresponding chakras.
Tantrics believe that by channeling sexual energy and your life force up and down the inner flute into the chakras, you will be able to destroy the physical, mental, and emotional roadblocks that are standing in the way of your spiritual bliss.
The inner flute — also called “the hollow bamboo” — is often envisioned as a channel that connects the genitals to the brain. Think of it as a train, with the chakras being on an axis that serves as the train tracks. By keeping all of your chakras in an open and receptive state, you give positive energy an easy passage through the inner flute.
