Eckhart Tolle's book A New Earth is about the need for a new consciousness and a new way of living on earth. He believes that humanity is at a crossroads and that we need to choose between two options: continuing on our current path, which will lead to self-destruction, or creating a new earth based on love, compassion, and mindfulness.
Tolle argues that our current way of life is unsustainable and that we are heading towards catastrophe. We are consume too much, we are polluting the planet, and we are destroying the natural world. Our egos are out of control and we are constantly in conflict with each other. We have lost touch with what it means to be truly alive.
Tolle believes that the only way to save ourselves from destruction is to awaken to our true nature as spiritual beings. We need to connect with the source of all life - which he calls the eternal Now - and live in harmony with it. Only then can we create a new earth where all beings can flourish.
