Vedic belief systems are historical predecessors of Hinduism. Vedism evolved into the paths of Yoga and Vedanta. Vedanta represents the philosophy of the ancient scriptures of India – the Vedas. This Vedic literature consists of the Upanishads, the Bhagavad Gita, the Puranas as well as many other texts, hymns, and writings. A cornerstone of the teachings is the ultimate identity of the individual soul with the Supreme Soul. Vedanta teachings also assert that with sincere and intense effort, the highest illumination is attainable to all.
