Threads of Eternity: Unlocking the Sacred Knowledge of Sanatan Dharma is a comprehensive exploration of one of the world's oldest spiritual traditions, designed to bridge the ancient wisdom of Bharat with the complexities of the modern world. Spanning over 800 pages, the book serves as a "humble gateway" into the vast ocean of Vedic knowledge, covering foundational principles such as Dharma (righteousness), Karma (action), and the cyclical nature of time, alongside deep dives into sacred scriptures like the Vedas, Upanishads, and the Bhagavad Gita. Beyond mere philosophy, it illuminates the scientific and cultural contributions of ancient Indian civilization—including advances in mathematics, medicine, and sacred geometry—while offering practical spiritual tools like meditation and the four paths of Yoga for contemporary self-realization. Authored with a particular focus on guiding today's youth toward identity and purpose, the work seeks to foster a vision of global harmony and environmental sustainability rooted in the eternal principle of Vasudhaiva Kutumbakam—the world is one family.
