Delhi Chief Minister Arvind Kejriwal said on Wednesday the controversies over spiritual guru Sri Sri Ravi Shankar's Art of Living (AoL) event should now end.“Now that NGT (National Green Tribunal) has given its verdict, all politics and controversies around AoL event should be put to rest,” he tweeted.“It is a huge cultural event wherein people from 155 countries are coming. Delhi welcomes all guests,” he said.The NGT slapped an initial fine of Rs.5 crore on the Art of Living foundation but declined to stay the holding of the sprawling World Culture Festival on the fragile Yamuna flood plain. It also pulled up the central government, saying the authorities had failed to discharge their duties.The tribunal also imposed a fine of Rs.5 lakh on Delhi Development Authority (DDA) and Rs.1 lakh on the Delhi Pollution Control Committee (DPCC).
