What is the Middle Way?
In the quote above, Rumi illustrates a nature-based view of existence free from extremes, a kind of Taoist liberation discovered to be balanced and within us. A kind of middle way. Taoism itself is sometimes called the "middle way" and so is Buddhism. Both traditions, unlike the Judea-Christian worlds of the Middel East, are non-theistic. They neither attempt to find a path toward God nor claim to follow commandments She might have set forth, but instead find their liberation in the inherently personal way-seeking practices of meditation or qigong, and in philosophies eminently sensible to individual study and application.
As for Buddhism, the fundamental elements of the middle way are present in the methods by which the Buddha gradually discovered it. Living the palace life of hedonistic pleasure sheltered from pain, young Siddhartha, in order to seek greater meaning, fled from his privileges and took up various practices of the ascetics of his time; fasting and other deprivations. Eventually he found that the practices of self-denial only led to greater duality - a war against the senses - and confinement. Starved and weakened from fasting, in the moment a young girl gave the Buddha milk to drink he revived into his first middle way revelation: that both hedonism and self-mortification were seductive but do not lead to liberation.
From this initial discovery, the middle way teachings evolved through the Buddha's own sermons as well as countless discourses that followed his over the centuries. The most central (no pun intended) of all middle way teachings concerns the opposing views of eternalsim, which deems everything to have a true meaning and nihilism, that nothing means anything. Both views possess compelling arguments and everyone, at times, falls subject to them. Transcending them is daunting since they form the unconscious conceptual structures of our world view. For instance, the conquistadors of Christian Spain had little qualms enslaving or murdering the inhabitants of Peru and Bolivia. Belief systems enabled them to be both theistic, convictions that non-Christions did not possess souls, as well as nihilistic, believing that it was of no consequence to slaughter the peoples of the New World.
Emerging from such diverse influences as the industrial revolution, Nietzsche's death of god, The Holocaust, the aesthetics of post-modernism, the H bomb and environmental catastrophes, our own epoch is characterized by a pervasive and pessimistic nihilism. Heidegger's famous quote "To be a poet in a destitute time means: to attend, singing, to the trace of the fugitive gods" proclaims how, as we've taken up the beliefs of scientific materialism, we've lost our experience in the unseen or invisible world. We have lost conviction in the magicall dimensions of the world: shamanism, the angelic realms, the gods as the Greeks knew them, etc.
I once asked the late Buddhist master Traleg Kyabgon Rinpoche about the pervasiveness of nihilism, even among Buddhists:
Eternalism is also pervasive in modern life. This takes the form and the perenial belief that we will not die, the subtle sense that we have an unlimited future. This internalized belief causes us to put any kind of discipline into the future, that we will finally begin meditation in earnest when we retire, or when we've built a beautiful shrine room in our back yard. In terms of artistic discipline, Charles Bukowski nailed this in a poem written to a woman who will begin creating as soon as she moves into her new-found studio with lots of "space and light":
Another highly useful aspect of the middle way are teachings that apply to meditation practice itself. Chogyam Trungpa described it as "not too tight, not too loose." What this means is easy to understand though not always easy to recognize in ones own practice, since, like theism and nihilism, each of as tend to fall into one of the extremes, making it difficult to see our own practice with fidelity. "Not too tight" means not too much effort, an excess of which brings tension rather than ease, self-consciousness rather than freedom from small self. "Not too loose" means enough exertion to stay awake, to not be constantly drifting into discursive thought, to not becoming simply dull.
In closing, we might turn to the words of the Buddha himself: "The middle path, O Bhikkus, avoiding the two extremes, has been discovered by the Tathagata - a path which opens the eyes, and bestows understanding, which leads to peace of mind, to higher wisdom, to full enlightenment, to nirvana."
