The Buddhist teaching of emptiness (śūnyatā) can completely transform how you view life and yourself. Here we trace this life-changing insight from its original exposition by the Buddha, through the Mahāyāna teachings of Nāgārjuna, the Yogācāra scholar-monks, all the way to the doctrine of the Tathāgatagarbha (Buddha Nature). As we explore the many twists and turns of śūnyavāda (the teaching of emptiness), we find a rich diversity that nonetheless keeps returning us to one and the same profound insight about the nature of 'things' and 'selves'. We cover much ground here, including the no-self teaching, whether Buddhism is a form of nihilism, the union of opposites, the interdependence of things, and the nature of conscious awareness.
