The Pran Pratishtha of Ram Lalla in Ayodhya is as significant as August 15, 1947, and heralded the cusp of a change of an era towards Ram Rajya and national development, Tamil Nadu Governor R N Ravi said on Monday. Describing the grand event as a “once in a lifetime experience”, he said the arrival of Ram Lalla heralded the cusp of a change of an era. “And I would say this day is as significant as the 15th of August 1947 when we became independent from foreign control. The alien powers which colonised us left,” Ravi said addressing an event “Chennayil Ayodhya” here.
