In the heart of Old Delhi, amid the historic lanes of Chandni Chowk near Cycle Market and Esplanade Road, stands a 300-year-old spiritual sanctuary — Shri Prachin Narsingh Hanuman Mandir, lovingly known as Patthar waale Baba. More than a temple, this sacred institution is a living embodiment of unbroken Vedic tradition, spiritual resilience, and community service. For three centuries, it has preserved its sanctity, structure, and lineage — surviving the decline of the Mughal era, colonial transitions, and the evolution of modern India — without losing its spiritual core. Today, it stands not only as a Siddha Peeth (center of spiritual power) but also as a pillar of social welfare and humanitarian service.
