Spiritual leader Dada J P Vaswani, head of the Sadhu Vaswani Mission, died at the age of 99 on Thursday due to old age-related ailments.

“He had been admitted to a private hospital in the city for the past few days and was discharged last night,” a mission member said, adding that Vaswani died on the mission premises on Thursday morning.

Prime Minister Narendra Modi, who was an admirer of the spiritual leader, took to Twitter to express grief over Dada Vaswani’s demise.

“I am saddened beyond words on the passing away of Dada J.P. Vaswani. He lived for society and served the poor and needy with compassion. Blessed with immense wisdom, he was passionate about educating the girl child, cleanliness and furthering peace as well as brotherhood,” he tweeted.

In another tweet, he wrote, “Dada J.P. Vaswani was a guiding light for me. About 28 years ago, I had the  honour of being with him at a world religions conference in USA. His clarity of thought stood out. In 2013 I had visited Pune to inaugurate a nursing college associated with him.”

Dada Vaswani would have turned 100 on August 2, 2018.

The mission was planning a mega centenary celebration from 31 July.

Born on August 2, 1918 in a Sindhi family in Hyderabad (now in Pakistan), Dada Vaswani, as he was popularly known, was the head of the Pune-based Sadhu Vaswani Mission, a non-profit organisation involved in social work and charity. The organisation runs educational institutions and hospitals in the city.
