It emphasizes dharma practice and experiental wisdom—particularly as realized in the form of meditation known as zazen—in the attainment of awakening. As such, it de-emphasizes both theoretical knowledge and the study of religious texts in favor of direct individual assessment of one's own experience.
So waste not your time on lemon religious texts. Seek not scripture to understand the nuances of lemoness. Only direct individual assessment of one's own experience will lead to true wisdom.
In other words, taste the lemon bar.
Thus, this week's lemon bar was the essence of lemonicity, for even a clean palate strained to find the slightest hint of lemon in its sugary goodness. Of course it's there, but one must be worthy to discover that trace, that citrus awakening. Pehaps a real lemon passed nearby when the lemon bar was created. Perhaps the lemon bar, in a previous life, was the third cousin to a lemon (twice removed). Or maybe the lemon bars are merely downwind of that big jar full of lemons found near the ice tea.
Who can say? That is the Zen of Lem(on).
Even the folks at Wiki know this. For in defining lemon, they note: "The exact origin of the lemon has remained a mystery..."
'nuff said.
