The Bhagavad Gita has served as a guide to liberation for over two thousand years. It advocates an integrated path of action without attachment to results. It has inspired and influenced Western thought since the first translation over two hundred years ago. Poets, philosophers, thinkers, and scientists have attested to its wisdom and life-changing impact. The Upanishads are the oldest spiritual teachings of the forest sages of India. They are the realization of an absolute Being called Spirit or Atman. They try to answer all of our deepest questions and doubts to provide a path towards Self-Realization through knowledge and wisdom. Purohit Swami was a dedicated pioneer in spreading the wisdom of India. He moved to Britain in the 1930s at the behest of his spiritual teacher. He collaborated with the Irish poet W.B. Yeats on the translation of the Upanishads.
