After several days in a Pune hospital for undisclosed ailments, Vaswani returned to his mission and died on 12 July 2018. He died three weeks shy of his 100th birthday.
Vaswani's health began to decline in May 2010, when at the age of 91, he fell and fractured his hip while playing ping-pong with children in Panama. He never fully recovered from the injury and was confined primarily to a wheelchair the rest of his life.
