In Thailand Ajaan Panya’s remains were cremated at Baan Taad Forest Monastery. "His funeral ceremony was the largest event ever held there—an estimated 50,000 people attended to pay their final respects, including over 4,000 monks. Something extraordinary occurred on the day of his cremation. The sky was clear and cloudless. Yet, on 3 separate occasions, a circular rainbow appeared in the clear blue sky, each time encircling the sun like a large, luminous halo. The rainbow first appeared as his casket was being placed on the funeral pyre; it appeared again later when his life story was being read aloud; and yet a third time when Ajaan Mahā Boowa lit the funeral pyre. It was as though the power of his spiritual attainment had created an external, visual image to reflect the depth and subtly of his virtue for all to see"
A miraculous event also took place when Ramana Maharshi passed. At that moment a shooting star, vividly luminous moved slowly across the sky. This was witnessed by many thousands of people in various parts of India.
It appears that when an enlightened being passes there can be unusual, even extraordinary phenomena that manifests for all to see.
