The Great Vow of the yogi, Maha-vrata is ahimsa, non-injury to oneself and others and implies that we love one another; it is essentially interwoven through the yamas and niyamas, the restraints and daily observances often overlooked by those who see yoga as no more than a form of body culture. These principles on which yoga is structured are integral to the cosmic body of light which reaches from heaven to earth and often ignored when they interfere with private purpose. Hence yoga can be harmful when releasing latent and suppressed energies which feed less than the highest. Sin can be defined as missing the mark; which the Self aware yogi becomes aware when not acting in accord with his true nature. It is at the end of a life that the sound geometry of the universe sifts out the untruth collected during a lifetime, so that each rings true and takes their rightful place in the cosmic evolution of planet earth.
Hatha yoga evolves a step at a time toward the realisation that we are not just a chemical body but have an essential energy or light body that organises and patterns who we are from the inside out. There is no light that is not spirit as light is a vibration of field energy, and we are truly condensed light. Light is not a blind un-feeling energy, it is sentient power and a symbol of your intelligence. It is meditation and study that has brought to light the yamas and niyamas and which once established form a positive and developmental link between spirit and the world of time.
