1. Rajput Culture and Intellectual Tradition

Jantar Mantar was built by Maharaja Sawai Jai Singh II of the Kachwaha Rajput dynasty.
For Rajput rulers, governance was not limited to warfare—it also required mastery over timekeeping, astronomy, and cosmic alignment.
Jantar Mantar reflects this enlightened Rajput belief that knowledge was a form of power and duty.

2. Connection with Social and Religious Life
