This is a valid perspective because the purpose of yoga is to tune up the body with respect to energy flow and availability. It is the physical maneuvers done in yoga practice that help to stimulate the energy centers and the meridian system in the body and help to dislodge accumulated negative energies that might begin to impede energy flow and its interchange between the meridian systems and the nervous system and other tissues of the body. The primary purpose of yoga is optimization of energy distribution and a restoration of energetic balance and optimal supply of energy. It is not the most rapid and efficient way to do so, but can be helpful as a self-administered practical tool. But as with other forms of energy healing, yoga will bring only temporary relief because life will bring renewed trauma, renewed stirring of karmic liabilities that will cause inner discord and a buildup of negative energies once again, and likely there will be ongoing manipulations by spirit attachments, or new ones if a person has had a successful clearing by a practitioner. This simply reflects the reality that the body, like an automobile, needs regular tuneups and maintenance to keep it in trim.
