Hinduism is the term often used for Hindu Dharma. The ancient name for Hinduism is Sanatan Dharma or Vedic Dharma. Whosoever wants to be a Hindu and follows the basic tenets of Hindu Dharma can be a Hindu. It is all-inclusive. The word “Dharma” is derived from the root “dhri”, which means to integrate, to uphold, to sustain. Dharma is the natural law; the law of being that governs this entire universe and all its components. Thus Dharma means ‘that which sustains you.’
