畫家藉由各類繪畫媒材，表現出個人對「禪」的體悟，所呈現出的作品可謂之「禪畫」，換言之，「禪畫」的作者可以是「禪僧」或「禪師」，也可以是「悟禪者」，其作品樣貌各異，但所流露的共通特色不外乎天真率性，因為天真率性，所以自在忘我而不做作。筆者所熟識的葉世強就是這樣的畫家，葉世強並非禪僧或禪門大師，但他創作時的天真率性，與作品中充滿的濃厚禪意，使人無法懷疑他確實是個「悟禪者」。歷代工於書畫的禪僧與悟禪者甚多，傳世佳作亦不乏其例，但提及當代的禪畫家，吾人無法忽略葉世強。筆者自2009年與葉世強熟識至今，交往頻繁，知其為人，觀其作品，屢屢給筆者莫大的震撼與感動。基於葉世強特殊的人生際遇與孤高的人品，使其禪畫呈現出異於他人的特殊風格，筆者在本文中擬從「油彩與禪意」、「作品的多樣性」、「平凡與簡單」、「空靈與孤寂」、「似與不似之間」、「非邏輯」、「返璞歸真」與「迅速與隨意」等八個方向，嘗試列舉作品分析說明葉世強的禪畫特色，並藉以對當代禪畫有一翻新的體悟。
