艺术中没有必须，因为艺术是自由的。

It is sadder to find the past again and find it inadequate to the present than it is to have it elude you and remain forever a harmonious conception of memory.

The dead are not gone. They are simply not here.

儒家所谓，“纵心所欲不逾矩”，道家所谓，“无为”，佛家所谓，“清净虚空”，其实说的都是一个道理，就是精神上的自由自在的状态。达到这种境界，就消解了得与失、荣与辱的界限，一切的一切就如同“庭前花开花落”、“天上云卷云舒”一般自然而然，荣辱不惊，无忧无惧。
