Ernest Holmes wrote "The Science of Mind" and created the Religious Science spiritual organization (NOT Scientology!) promoting "a world that works for everyone." Another catch-phrase of the organization is "change your thinking, change your life." There is a deep knowing that we do have the power inside us already, as Ms. Rowling states.
We are living through some rough times, and it can be painful to watch. Nevertheless, I am hopeful. I believe the pandemic has awakened us in so many ways, as have the deceitful, greedy, misogynistic, violent and racist behaviors of Trump and his supporters. Old energy is dying, kicking and screaming. I believe the concerted effort of the Republican party to keep us sick, dumb and poor will not prevail. New generations, with new energy, are imagining better, and with that, blessed change is happening. Birthing anything, including a new consciousness, is a tough experience. Fear abounds, but we can have faith and hope because we have "the power to imagine better."
