According to the Upanishads, the body is a temple and the one residing in it is the Lord Himself. Humans have endeavored to replicate this message through the construction of temples. The heart is the cave where the soul dwells and the cave is the temple's sanctum sanctorum where the deity resides - in darkness and stillness. In all faiths, light is the archetype of transcendence. In the temple, it is only with the light of the lamp, purposefully raised, that the magnificent presence of God is revealed. In us, god is discovered with the light of knowledge: when it floods the cave, it banishes the darkness, illuminating and making the unknown gloriously known. What is this light? What does it disclose? How is it attained? With gratitude and humility, 'Darkness to Light' provides answers and makes suggestions. This book is a humble offering of gratitude at the feet of the great master Pujya Gurudev Swami Chinmayananda, founder of Chinmaya Mission, who has ignited the spark in the hearts of seekers worldwide.
