Consciousness: witness (we are the eyes and consciousness to what is/ has/ will occur), transform (we can make changes where there is need, will and consciousness), dream (each individual can dream there own story), resurrect (we can resurrect things we regret having lost - the salmon, forests, and ourselves)
