Hinduism is the world's third-largest religion. It is an Indian religion and dharma, or way of life, widely practised in the Indian subcontinent and parts of Southeast Asia. Hinduism has been called the oldest religion in the world, and some practitioners and scholars refer to it as Sanātana Dharma, "the eternal tradition", or the "eternal way", beyond human history. Scholars regard Hinduism as a fusion or synthesis of various Indian cultures and traditions, with diverse roots and no founder. Its followers, known as Hindus, constitute about 1.15 billion, or 15–16% of the global population. Hinduism is the most widely professed faith in India, Nepal, and Mauritius. It is also the predominant religion in Bali, Indonesia. Significant numbers of Hindu communities are also found in the Caribbean, Southeast Asia, North America, Europe, Oceania, Africa, and other countries. The Undergraduate Certificate in Hindu Religion and Culture provides students with an opportunity to understand Hindu philosophy, ethics, rituals, cultural norms, and practices; and to develop hands-on tools for Christian engagement with Hindu adherents.
