Book excerpt: In the first US edition of Satish Kumar's classic book, we rediscover how our spiritual and social well-being connects to that of our planet. Internationally-respected peace and environment activist Satish Kumar has been gently setting the agenda for change for over 50 years. As 350.org founder Bill McKibben says, "There is no one on the planet better-equipped to make you think and rethink how you're living and how you might change." The age of sustainability is grounded on the knowledge that we ourselves are very much part of nature; that what we do to nature we in fact do to ourselves; and that the earth has a soul, which we share. Drawing on the example of Rabindranath Tagore, Kumar advocates living with awareness that our personal choices have political and poetic resonance. In this book, he inspires readers with the knowledge we are all leaders and can create change in our structures and mindsets for lasting peace and a sustainable culture and society. Celebrating an emerging global consciousness that reveres nature, the book explores how, as a global society, we need to embrace diversity and be aware of our role as pilgrims on this earth. Joyful and heart-centered, Satish Kumar reminds us that to bring about change in the world, we must embody the change we wish to see.
