"Hindu" can refer to both a cultural and religious identity.
Religiously, Hinduism is one of the world's oldest religions, with a rich and diverse set of beliefs and practices. It encompasses a wide range of philosophies, rituals, and traditions. Unlike many other religions, Hinduism does not have a single founder or a specific set of doctrines, making it a highly diverse and pluralistic tradition.
Culturally, "Hindu" can also refer to people who identify with the cultural practices and traditions associated with Hinduism. It is important to note that being Hindu can be both a religious and cultural identity. Hindu culture has contributed significantly to art, literature, philosophy, science, and other fields throughout history.
