This has been on my mind for a couple weeks now..
In Kriya and kundalini yoga there is emphasis on concentration within the spinal cord and its chakra trigger points as they are called. The actual vortex of energy is called a kshetram.
This is a bit backwards because kshetram litterally means place. The chakra is the wheel, so the vortex of energy should be the chakra.
So what has been more effective for you guys? Concentrating on the kshetram or the chakra trigger point in the spine?
