The middle chakra is the heart chakra, with three below and three above, our baser or lower frequencies and our more ethereal higher frequencies.
The alchemy of the heart melds these, and composes the music of the heart from this full range of the lowest to the highest tones of our being.
Love is what brings it all together.
When we move forward with love, we have all our being working in harmony tuned by the heart. We are literally more composed, if you will.
Yoga and meditation help to tune us to this love frequency and get us moving to it.
