An evidence-based guide to Hindu philosophy for ex-Muslims, atheists, and agnostics, exploring ethics, karma, cosmology, and spiritual inquiry through reason and verifiable sources. Sanatana Darshana: A Ready Reckoner for Hindu Dharma is designed for readers who want to understand Hindu philosophy through evidence rather than belief. To our knowledge, this is the first comprehensive guide aimed specifically at non-believers, presenting Hindu ethics, philosophy, cosmology, and spiritual practices through reason, historical references, and scientific parallels rather than faith-based argumentation. Unlike other guides that aim to convert or defend faith, this ready reckoner focuses on education and rational inquiry. It explains key concepts such as karma, dharma, caste, gender roles, God, cosmology, and meditation practices using clear explanations and accessible language. The framework also provides a model that other faith traditions can use to create their own ready reckoners, promoting interfaith understanding, critical thinking, and balanced religious literacy.
