Chogyam Trungpa writes in The Lion’s Roar: An Introduction to Tantra:

There is a story about a man who was stealing a bell, and he covered his own ears so that no one would hear it ringing. We plan ways to hide our own pain, thinking that nobody will know. Realizing the fundamental suffering, the private parts that we stupidly try to hide—being so intelligent and so stupid at the same time—is the first step of the journey. Discovering that this hidden factor is exposed already is the highest thing of all. It is the real truth, and if we acknowledge it, it is a beautiful truth, a fantastic truth.
