王羲之草书《思想帖》，出自明刻《馀清斋帖》之续帖第一册。此帖也刻在《戏鸿堂帖》、《玉烟堂帖》、《郁冈斋帖》、《淳熙续帖》、《宋拓谭帖》等等汇帖之中。

释文：羲之顿首，不复见君。甚有思想，得告慰之。故吾乏气兼欲廗下，忧深不佳，尅面。王羲之顿首。 

Wang Xizhi's cursive "thought calligraphy" comes from the first volume of the continuation of mingengraved "yuqingzhai calligraphy". This post is also engraved in Xihong Hall Post, Yuyan Hall Post, Yugang Zhai post, Chunxi continuation post, song tuotan post and so on. Interpretation: Xizhi's head suddenly, no longer see you. I have a lot of thoughts. I can be comforted. Therefore, I am short of breath and want to go down. I am worried deeply and have a bad face. Wang Xizhi suddenly turned his head.
