PATNA: A former student of DPS Patna wrote to the Prime Minister about the deteriorating condition of a 70-year-old art work, a 100ft long scroll, depicting the story of Lord Buddha's life from Birth to Enlightenment. Sanghamitra (24), currently studying at George Washington University , was concerned that her grandfather's magnum opus would be lost to the vagaries of time if it wasn't restored urgently. The PMO has acted on her request to restore the piece of art.The scroll was drawn by Buddhist artist Upendra Maharathi who died 40 years ago. He designed the peace pagoda atop Ratnagiri hill at Rajgir near Griddhakuta hill, where Buddha preached the 'Lotus Sutra' for seven years.Lucknow-based National Research Laboratory for Conservation of Cultural Property has been tasked with the job to restore the scroll kept at the world peace pagoda at Rajgir. Once the restoration work is done, it would be displayed at the National Gallery of Modern Art in New Delhi.Most of Maharathi's paintings, over 800 of them, adorn the walls of the National Gallery of Modern Art while there are other works that are part of various private collections, museums and government houses. A 250-ft-long stone panel designed by him adorns the walls surroundings the Mahabodhi Mahavihara at Bodh Gaya.Sanghamitra told TOI from Washington, "It is to the credit of the PM that even amid the deluge of concerns that are often directed towards a man of his stature, a solicitous ear was turned towards this concern of mine and a fine piece of India's cultural treasure was saved. I am grateful to him."
