Book excerpt: Millions of Americans today practice the asanas, or postures, of yoga, but many are unaware of the profound spiritual teachings at the heart of yoga’s ancient source scriptures. In this remarkable anthology, acclaimed Vedanta teacher Dave DeLuca presents 166 sacred passages from some of India’s most revered yoga scriptures — the Upanishads, the Bhagavad Gita, the Yoga Sutras, the Bhakti Sutras, the Astavakra Samhita, and the Srimad Bhagavatam — along with teachings by two of the most beloved yoga masters of the modern era, Sri Ramakrishna and Swami Vivekananda. This combination of ancient wisdom and modern commentary makes Sacred Jewels of Yoga an invaluable introduction to the scriptural treasures of ancient India and a priceless resource for inspiration, illumination, and guidance.
