We are in the midst of a monumental transformation in human civilization, akin to a metamorphosis. Just as in Nature where the caterpillar gorges excessively before forcibly undergoing a metamorphosis in the chrysalis, we over-consuming humans are reaching a point of being forcibly transformed within the cocoon of our finite planet into compassionate, life-affirming butterflies. Vegan life-affirming butterflies. Carbon Yoga weaves a narrative through the events of the past to show that such a vegan metamorphosis is inexorable and that this system change will occur within the next decade, both from a scientific perspective and from a religious and spiritual perspective. The narrative proposes an evolutionary purpose for humanity and for Western civilization. During the Caterpillar phase, humans unintentionally built all the tools and technologies needed to regulate the Earth's climate and organize an equitable global human society. But as a consequence, the Earth is marinating in ever accumulating toxic pollution even as ecosystems are degraded and the climate is changing. Now, we have no choice but to treat all Life as sacred in order to preserve that on which we depend for our own survival. Such a revolutionary change in human outlook has the added benefit of inducing spiritual awakening, resolving social justice issues, elevating our connection with all Life and improving human health and well being. It is only such a quest for "moral singularity" that will heal the Earth, regenerate Life and lead us to true global sustainability. Carbon Yoga is the second in a series that began with the 2011 book, Carbon Dharma: The Occupation of Butterflies. While Carbon Dharma was mainly about what we need to do, as a species, to reach sustainability, Carbon Yoga takes this understanding of ethical and environmental righteousness (Dharma) and suggests how we can go about doing it (Yoga).
