The Ram Temple in Ayodhya witnessed a spectacular event on Ram Navami as a beam of sunlight, known as 'Surya Tilak', was delicately directed onto the forehead of the revered Ram Lalla idol. This unique phenomenon, achieved through state-of-the-art engineering, marked a significant blend of tradition and innovation at this sacred site.

Engineering Excellence: Designing the 'Surya Tilak' Mechanism

Led by a team of ten esteemed Indian scientists stationed at the Ram Mandir, this awe-inspiring achievement was made possible by the creation of a specialized apparatus named the 'Surya Tilak mechanism'. This apparatus comprises a sophisticated arrangement of mirrors, lenses, and a tilt mechanism designed to capture and redirect sunlight with pinpoint accuracy.

Dr. Pradeep Kumar Ramacharla, Scientist and Director at the Central Building Research Institute (CBRI), Roorkee, elucidated the intricate workings of this opto-mechanical marvel. The system includes four mirrors and four lenses strategically positioned within a tilt mechanism and piping infrastructure. By manipulating the tilt of these mirrors, sunlight is meticulously channeled and focused onto the idol's forehead, creating the sacred 'Surya Tilak' during the auspicious hours of Ram Navami.

Precision Engineering: The Science Behind the Ritual

The 'Surya Tilak mechanism' not only embodies scientific ingenuity but also upholds the sanctity of the traditional ritual associated with Ram Navami. It is carefully crafted using durable materials like brass and high-quality mirrors and lenses. This apparatus ensures sustained performance and accuracy year after year. Critical components such as pipes, elbows, and enclosures are meticulously coated to prevent light scattering, guaranteeing a focused beam of sunlight for the ceremonial anointment.

Furthermore, advanced technologies such as infrared filter glass are employed to mitigate heat waves and safeguard the idol from direct solar exposure, underscoring the meticulous attention to detail and safety considerations inherent in this groundbreaking engineering feat.

To ensure the timely occurrence of this auspicious ritual on the fixed date of Ram Navami according to the lunar calendar, intricate arrangements utilizing 19 gears were implemented, completely independent of electricity, batteries, or iron-based components.

Similar 'Surya Tilak' mechanisms can be found in certain Jain temples and at the Sun Temple in Konark, although they are engineered with distinct designs and approaches.

The 'Surya Tilak' event not only illuminates the Ram Temple but also illuminates our path forward, inspiring a deeper appreciation for the intersection of science, spirituality, and tradition.
