There is an idiom in Marathi – अटकेपार झेंडा रोवणे… literally “Taking the flag beyond Atak”. Figuratively it means one has pushed oneself to achieve the impossible. Atak was the northernmost town in the Maratha Empire when it was at its zenith in the mid 18th Century. The fact that a Hindu power from the Deccan could hold sway at the foothills of Himalayas was unthinkable at the start of that century.
