In the high passes of the Himalayas, where Ladakh's rugged peaks meet the sky, over 100 people, mostly retired Indian Army soldiers and women, walk with unwavering determination. Each day, they cover about 25 kms, singing in unison the song, “Hum Honge Kaamyaab Ek Din...Mann Mein Hai Vishwas, Poora Hai Vishwas” (We shall overcome someday, there is faith in the heart, complete belief). Ladakh's celebrated innovator Sonam Wangchuk says their resolve remains as steadfast as the mountains themselves. Draped in a white jacket with the Indian tricolour pasted on its right side, he gazes at the high passes. "At these heights, the weather changes with every breath," he says, "but our resolve to march all the way to Delhi for the Sixth Schedule remains steadfast."
