Zen philosophy?

Philosophy is oftentimes regarded as an artificial covering, at best-reflecting approximations. One Webster definition is “...a search for a general understanding of values and reality by chiefly speculative rather than observational means.” Another is “...a theory underlying or regarding a sphere of activity or thought.” 

To many—especially Westerners—Zen is seen as an esoteric philosophy, with little relevance to everyday life. This view hasn’t changed much since The Buddha walked the earth 2,500 years ago and perhaps for a good reason. Theories about life rarely match reality. They may be useful in limited mapping situations, but it is impossible to develop a theory or philosophy which fits life perfectly.

Theories and philosophies should always be measured against the standard of reality. Knowing something as a bone-embedded fact always wins the day against speculation. The proof of such comparison thus comes down upon how reality is understood. Are our senses to be trusted? Do we see clearly (without bias or distortion)? Do we know what is real? Seeing from within a cloud of obscurity is not the same as a vision on a clear day, and for this reason, the practice of Zen is concerned with clearing away the ego-mind to reveal our untarnished original mind. In the Lankavatara Sutra, the Buddha and a bodhisattva named Mahāmat spoke about these matters and said...

“To philosophers, the conception of the Tathāgata-womb seems devoid of purity and soiled by these external manifestations. Still, it is not so understood by the Tathāgatas—to them, it is not a proposition of philosophy but an intuitive experience as real as though it was an amalaka fruit held in the palm of their hand.”

The Tathāgata-womb is self-evident. The Sanskrit word used is Tathāgatagarbha, which is rendered as the Buddha womb. The term Tathāgata means—one who has thus gone (Tathā-gata) or one who has thus come (Tathā-agata), the import is one who has transcended the ordinary view of reality. Is this birth-place in some distant place? Zen teaches that it is ubiquitous; there is no coming nor going since it is impossible to be where it is not.

This is, of course, a difficult thing to embrace. When we think of the exemplary and pure nature of a Buddha, and compare this incomparable state to our own, it seems impossible to accept that we too contain this nature (e.g., Buddha-Nature) but that is what Zen teaches. But it is one thing to think such a purity resides in us, as a philosophical consideration and quite another to experience it intuitively. When the latter occurs, all doubt goes away, and you are transformed forever. Then only do you truly know yourself as one who looks into their own heart and finds eternity.

In this sense, Zen is not a philosophy. It is opposed to speculation and philosophy of all kinds. The preeminent focus of Zen is to intuitively experience the purity and clear vision that comes from our very own being. And when that happens, reality is seen in a radically new way.
