Vedanta is one of the world's most ancient religious philosophies and one of its broadest. Based on the Vedas, the sacred scriptures of India, Vedanta affirms the oneness of existence, the divinity of the soul, and the harmony of religions. Vedanta is the philosophical foundation of Hinduism; but while Hinduism includes aspects of Indian culture, Vedanta is universal in its application and is equally relevant to all countries, all cultures, and all religious backgrounds. The unity of existence is one of the great themes of Vedanta and an essential pillar of its philosophy. Unity is the song of life; it is the grand theme underlying the rich variations that exist throughout the cosmos. Whatever we see, whatever we experience, is only a manifestation of this eternal oneness. The divinity at the core of our being is the same divinity that illumines the sun, the moon, and the stars. There is no place where we, infinite in nature, do not exist.
