There is a difference between “the actual world” and our idea of the world in our minds. Despite the scientific realists’ claim that scientific knowledge resembles real (natural) entities, many philosophers of different epochs and cultural realms concluded that we can’t be that certain of what we believe is the “reality”. This ranges from Daoists (the Dao stands for the ultimate reality that is in contrast to the human world that is perceived, explained and communicated by names (language)), to Indian (Hindu) worldview with two truths (ultimate reality and phenomenal (common sense) reality), to Kantian metaphysics (things-as-they-are (Dinge-an-sich) and forms-of-view (Anschauungsformen)), to constructive realism a la Friedrich Wallner (actuality vs. lifeworlds and microworlds). Nobody, however, expressed this difference more aptly than Gautama-Buddha, mounting in the First Noble Truth (“Life is suffering“). I understand suffering (dukha) in the Buddhist sense as the deviation between our idea of the world as the result of our deluded minds and the world as it really is. This is what he means with ignorance. Let me elaborate a little further on that.
In my tree of knowledge, I depicted our mental and cognitive features (and all they entail) including the experiences we make through them as the roots, the process of sense-making and meaning-construction as the channels in the trunk of the tree, and the manifestations of our worldviews, beliefs and values as the branches. This can be a powerful illustration to explain the essence of Buddhist worldview. The core of Buddhist philosophy is the scheme of the “12 links of interdependent co-arising“. Basically, it teaches that due to our ignorance we believe in the permanence of isolated separated entities, including ourselves (or: our self). We believe that “what we see is really there” (which, from an evolutionary perspective, is probably helpful for survival), which arouses our desires in a way that we judge what is “good” or “bad” for us so that we seek for some things (attachment) and avoid others (resistance). The desirability and non-desirability of things, however, is an illusion. It is formed by the framework of our past experiences and our vision of the future (driven by the fear of death). Buddha, here, elaborates on the roots (in my picture): He claims that the roots are grown in a rigid and inflexible way. We rely on perception tools that are limited (six senses, each limited to certain ranges of physical properties such as wavelengths (seeing), frequencies (hearing), molecular concentration (tasting and smelling), etc.). We are aware only of what fits our experiential margin. Emotions and desires are shaped by forces that are beyond our control. Therefore, relying on our roots is the first factor of suffering.
Then, he explains what the flaws are with our choices of channels for meaning-construction. We are driven by concepts and intellectual reasoning, external forces like dogmas and paradigms, or psychological punishment- and reward-systems. Same as the roots, they are all deluded by the illusory conviction that our mental reality is identical with the actual reality. Society with all its institutions (science, politics, economy, organised religion, etc.), culture (with its modes of identification in separation from other cultures), and also individual personality (as the branches of the tree) are all built on this level of reality. Things are, however, different. There is nothing permanent and separated. Everything is connected in a complex net of conditionality, non-deterministic, non-teleological, non-reductive, non-dualistic, and therefore: empty. Shunyata (“emptiness“), as understood by Nagarjuna and later the Chinese Mahayana schools Huayan, Tiantai and Chan, is the fundamental metaphysics of the world. This is the ultimate reality. The worldly features that we create on the basis of our deluded “roots” deviate from this underlying ultimate reality to certain extents. The bigger that deviation the stronger our suffering.
Now, there are two ways to overcome this suffering. One works on the roots. We may plant seeds for the roots to grow in different ways. To use the metaphor of a famous movie: This means to “exit the matrix” of the mindlessly grown roots and actively form new sources for experiences and cognitive access to reality. The other way – but most often both ways have to be applied together – is a change of meaning-construction, or in terms of the picture: choose a different channel through the trunk. This is meditative contemplation and mindful awareness. In order to get closer to the ultimate reality, we need to let go of concepts, deluded rationality, mindless following of doctrines and rules (acquired through education and socialisation), and especially the illusion of an independent self that dominates our psyche. Only then will we be able to see through the complex network of cause-effect-relations (karma) and set ourselves free in (not from) its matrix. The Diamond sutra may help to understand the important point here: “Form is emptiness, emptiness is form.“. It sounds like a contradiction, but it is a rhetoric tool to describe the indescribable. Form (the things we perceive as independent objects or substance on the level of (deluded) common-sense reality) is actually empty (not outside the karmic cause-effect-conditionality), while it is exactly this metaphysical conditionality that brings about all which we interpret as form. This ontological understanding, with ourselves interwoven into the ever-changing web of the world fabric, will change our approach to life fundamentally! While the more traditional Indian Buddhists (Theravada schools) would probably state that there will be no more branches since enlightenment (that ontological break-through) leads to the other-worldly nirvana, I share the Mahayana view (esp. Tiantai) that enlightenment and nirvana are this-worldly phenomena from which we benefit within our lifetime. With an enlightened mind, our roots, the trunk and the branches all transform. We see our personality traits, emotions, fears, desires, and worldviews in the context of our past, our local surrounding (society, culture) and our cognitive capacities. We see how our past experiences form layers around our very core personality, the Buddha-Nature. In the next step, we disconnect the causal chains that control our decisions and choices. We see how sense and meaning are constructed in our mental processes and gain the ability to step back from it, question the strategies, apply different ones and get less dependent on the pre-shaped ones. Many branches, then, lose their significance and shrink. We see how others construct meaning and why they act like this or that within the thematic margins of certain branches, and we gain the empathic skills of compassion and loving-kindness.
