Sanatana Dharma, often known as Hinduism, is the world's oldest and most widely practiced religion. As such, it is regarded as a natural religion, which means that its tenets and rituals are open to anybody who is willing to study, reason, and experience them for themselves. Similarly, Hinduism is an indigenous religion that has been practiced in Asia for thousands of years and consists of a variety of philosophies and customs. With members from nearly every ethnic and national group and residing on every continent, Hinduism is now an international religion with majorities in India, Nepal, and Mauritius.
