《淮南子·道应训》
文王回去后，便用玉来装饰屋门、修筑起灵台、并挑选了不少美女，经常在灵台上奏乐寻欢，以此来等待纣王的进一步失误。
文王归，乃为玉门，筑灵台，相女童，击钟鼓，以待纣之失也。
After King Wen returned, he used jade to decorate the door of his house, built a spiritual platform, and selected many beautiful women. He often played music and had fun on the spiritual platform, in order to wait for King Zhou to make further mistakes.
