While I can force the farohad to allow me to tap its energies, and through trial and error we have been able to transfer that concentration of light into the Matrix, I am unable to control it once the energy is in the Matrix . Please note this because it explains why we cannot control the effects in the Matrix . The speed at which the light moves is beyond our capacities and the capabilities of the best deckers we have . The spirit’s lack of cooperation makes training the farohad impossible . Our best brains alone cannot match the speed and short-lived usefulness of these bursts of pure light .
