Sanatana Dharma is a Sanskrit term that means "eternal law" or "eternal order." It is the traditional name for Hinduism, and it is often used to refer to the underlying philosophy of Hinduism rather than any specific sect or denomination.

Sanatana Dharma is different from other religions in a number of ways. First, it does not have a single founder or prophet. Instead, it is based on a body of ancient texts, including the Vedas, the Upanishads, and the Bhagavad Gita.

Second, Sanatana Dharma does not have a single set of beliefs or practices. Instead, it is a diverse tradition that encompasses a wide range of beliefs and practices. This diversity is reflected in the many different sects of Hinduism, each of which has its own unique set of beliefs and practices.

Third, Sanatana Dharma does not emphasize the importance of conversion. Instead, it teaches that everyone is born with a certain dharma, or duty, and that the goal of life is to fulfill that dharma.

Finally, Sanatana Dharma is not a proselytizing religion. It does not seek to convert people to Hinduism, but rather to help people of all faiths to live a good and meaningful life.

In short, Sanatana Dharma is a complex and diverse tradition that is difficult to define in a few words. However, it is a tradition that is based on the principles of truth, compassion, and non-violence, and it has a rich history and culture that spans thousands of years.
