Although there are many approaches to religion, Chan is essentially about overcoming the hold of worldly desires, rendering them powerless to affect one. It involves casting off the ego and letting go of oneself. It means penetrating to the ultimate realm of nothingness, where there are no flowers or moonlight, yet where everything-flowers and moonlight included-exists in true abundance.
修行方法雖多，但在禪而言則不外於將凡心的作用封死，無法起作用；把我這俱生我執丟掉，懸崖撒手，絕後再甦，破到極致，無花無月，但無一物中無盡藏，這裡其實有花有月有樓台。
