Worldly afflictions are as extensive as an ocean, noisy and clamorous; but they all arise from the thoughts in your own mind. When not a single thought is conceived, you are liberated from them all.
Since it depends on one's own self, how hard could it be? Attaining Buddhahood shouldn't even take a finger snap.
