In a major boost to UP tourism, Prime Minister Narendra Modi is all set to open Kushinagar International Airport on October 20. Kushinagar is of significance to Buddhists all over the world as it is here that Lord Buddha is believed to have attained Mahaparinirvana after his death (2500 BE). It is famous for the Reclining Buddha image inside the Parinirvana Stupa. Prime Minister will participate in an event, organized to mark Abhidhamma Day. The day symbolises the end of three-month rainy retreat – Varshavaas or Vassa – for the Buddhist Monks, during which they stay at one place in vihara & monastery and pray. The event will also be attended by eminent Monks from Sri Lanka, Thailand, Myanmar, South Korea, Nepal, Bhutan and Cambodia, as well as Ambassadors of various countries. The inauguration of Kushinagar International Airport will be marked by the landing of flight from Colombo, Sri Lanka. Led by Namal Rajapaksa, son of Prime Minister Mahinda Rajapaksa, the Lankan delegation of over 100 Buddhist monks and dignitaries, including the 12-member Holy Relic entourage, is bringing the Holy Buddha Relics for Exposition. Built at an estimated cost of Rs 260 crore, the Kushinagar International Airport will facilitate domestic and international pilgrims to visit the Mahaparinirvana-sthal of Lord Buddha. The airport will also serve nearby districts of Uttar Pradesh and Bihar.
