Arun was the driver for his grandfather. He would take him from the ashram to the meetings in the city (about 13 miles) where his grandfather taught an extreme version of non-violent action called "Truth Force". Truth Force won the independence of the Indian nation against the well-armed English Army. 

When Arun dropped his grandfather off, he would usually do errands for the ashram and then return to pick his grandfather up after the meeting. 

On this evening, instead of doing his errands, he went to the cinema and arrived late to his grandfather's meeting full of excuses. 

His grandfather, in the kindest voice, told him: "I cannot accept a ride home from you tonight. I must contemplate what I did to cause a grandson of mine to lie." 

Arun drove slowly alongside his grandfather, pleading with him to get in the car, but his grandfather continued to walk and contemplate. 

By the time they arrived at the ashram, Arun understood that truth had the greatest power and, with this realization, he vowed to never lie again. 

He has kept his promise to this day. 

The power of truth can win a nation.
