Central to the private life of the Taoist is the art of concealment. In Taoism, to conceal does not mean to be aloof and disengaged. Rather, it means not to dazzle or make ourselves the focus of attention. Our modern culture encourages us to brag about our achievements and show off our wealth. Contrary to displaying their talents and abilities, Taoists cloak their knowledge, and even their wisdom, using them only at the appropriate place and time. The outlook that forms the foundation of the art of concealment is called hidden sky, which means concealing the skylike vastness of our wisdom rather than basking in its glory.
