When our awareness/consciousness is in one or more of these bodies, a state of "mind" arises. (However, from the meditative-body a state of "no-mind" can arise called Samadhi, which is beyond the embodied mind.)
You could think of mind arising like light passing through rain from which a rainbow "appears." In other words, mind is a multifarious reflection of what bodies our consciousness is in. But notice I said what "bodies" we're in rather than what body, for consciousness is usually divided into many of our bodies, dividing the light into an array of colorful experience that our being can experience integrally.
For example, music can be experienced physically, mentally, energetically, emotionally and spiritually.
The reason for it being off key is the gap. The reason for the gap is an aversion to something we need to surrender to, to observe, to fill with consciousness. It's something we need to go into but instead we avoid.
In avoidance we create a void. This is called Avidya -- duality. It's a state of separation/disharmony, which is the root cause of all dis/ease.
Basically, each feeling of dis/ease fits into one of these five bodies (koshas). This doesn't just mean, however, that you're not filling one of your bodies with enough consciousness. Actually, the neglect of one area often means too much attention is in another.
For example, if you're an emotional person, your consciousness/ attention/ awareness is probably stuck in your emotional body. Yoga therapy would help you to move some energy out of that body and into other areas so that you can deal with your issues with the integral wisdom of the whole being, including the spiritual or bliss body that taps you into powers beyond the self. But first you have to know these other bodies you have, first you have to strive to "know thyself."
Note: Yoga therapy is not usually a licensed practice, even though it's been used -- under simply the name of yoga -- as a therapy for thousands of years prior to western psychotherapeutic models. I'm working toward an M.A. in this field.
