My humble response to the above is 'none of the these'. For me his finest moment came in the late 1946 when with only a handful of his faithful companions he had rushed to Noakhali in East Bengal in a bid to protect the Hindus who were being victims of the worst kind of savagery at the hands of the majority Muslim community. Going on foot from village to village, unarmed and without any police protection, he and his companions applied a healing touch to the wounds, bodily and emotional, suffered by the Hindus. It was his piety, purity and friendliness which put some sense into the minds of even the most virulent tormentors of the minority community. But before that could happen he himself was attacked by a Muslim youth who could very well have killed him had he not heard Gandhi mumbling a prayer from the Quran. When the youth realised his madness he fell at the Mahatma's feet and begged for forgiveness. The great man patted him on the shoulder and told him not to mention the incident to anyone, otherwise the entire country would be rocked by Hindu-Muslim riots.
He brought sanity and peace to Noakhali by the sheer force of his character and that was his finest moment.
