flames

The discus Sudarśana, the rim of which is fierce like fire raging at the time of the destruction of the universe, whirls about when discharged by the Lord. Oh Sudarśana do completely and thoroughly burn down the inimical forces to ashes just as fire, helped by the friendly (favourable) wind, immediately consumes (heaps of) dry grass.
