Yoga works primarily with the energy in the body, through the science of pranayama, or energy-control. Prana means also ‘breath.’ Yoga teaches how, through breath-control, to still the mind and attain higher states of awareness.
The higher teachings of yoga take one beyond techniques, and show the yogi, or yoga practitioner, how to direct his energy in such a way as not only to harmonize human with divine consciousness, but to merge his consciousness in the Infinite.
The ordinary person’s energy is locked in his body. The lack of availability of that energy to his will prevents him from loving the Lord one-pointedly with any of the three other aspects of his nature: heart, mind, or soul. Only when the energy can be withdrawn from the body and directed upward in deep meditation is true inner communion possible.
