Across Buddhist traditions, liberation (nirvāṇa/nibbāna) is presented as the cessation of suffering through insight into the nature of reality. However, there appears to be substantial disagreement both within the tradition and in modern scholarship over whether this requires substantive ontological commitments. In the early discourses of the Pāli Canon, the Buddha famously refuses to answer speculative metaphysical questions (e.g., the “undeclared questions” in the Cūḷamālukya Sutta), framing the Dhamma as therapeutically oriented toward the cessation of dukkha. This has led some interpreters to read early Buddhism as anti-metaphysical or methodologically quietist. Yet the path itself seems to require insight into doctrines such as dependent origination paṭiccasamuppāda,anattā, and anicca. These appear to function not merely as pragmatic heuristics but as claims about how things actually are. Later traditions intensify this tension:- - The Abhidharma systems of schools such as the Sarvāstivāda develop highly detailed ontologies of dharmas, seemingly grounding liberation in precise metaphysical analysis. - In contrast, Madhyamaka, especially as articulated by Nāgārjuna in the Mūlamadhyamakakārikā, appears to deconstruct all ontological positions including those that might underwrite soteriology itself while maintaining that such deconstruction is indispensable for liberation. This raises a structural problem: If liberation requires “seeing things as they are” (yathābhūta-ñāṇadassana), does this not presuppose some metaphysical or ontological account of what ultimately exists or how phenomena are structured? Can a “metaphysics-free” Buddhism be coherent, or does the very logic of liberation require at least minimal ontological commitments?

Is there any mention of the fundamental building blocks of reality in Buddhism? Science tells us that we are made of atoms, which in turn are made of protons, neutrons and electrons, which in turn are made of quarks and so on. Does Buddhism reveal to us the absolute fundamental building blocks of reality and the Universe? If so, then what is the nature of those building blocks? I am 100% certain that the Buddha would have known the deepest nature of physical reality and answers to all the mysteries, humans have spent pondering since millenium. I know this question falls under the imponderable and thus doesn't aid me in relieving suffering in samsara, but still curious to know :) Peace.

Some months back I had written a comment (*not able to find it atm*) to a post in BSE which resonated with the following explanation of Enlightenment by Osho, that ' *Enlightenment is consciousness conscious of itself* '. But it was not taken well. The following is taken from his book, The Last Testament. I am very much in tune with this particular explanation and my practice also more or less depends on this. I just want to know is this accepted by any branch of Buddhism, whether Theravada, Mahayana or Vajrayana. > First, watch your actions of the body. > > Second, watch your actions of the mind: thoughts, imaginations. > > Third, watch your actions of the heart: feelings, love, hate, moods, sadness, happiness. > And if you can succeed in watching all these three, and as your witnessing grows deeper and deeper, a moment comes that there is only witnessing but nothing to witness. > > The mind is empty, the heart is empty, the body is relaxed. **In that moment happens something like a quantum leap. Your whole witnessing jumps upon itself. It witnesses itself, because there is nothing else to witness. And this is the revolution which I call enlightenment, self-realization.** Or you can give it any name, but this is the ultimate experience of bliss. You cannot go beyond it. ****Please no personal attacks on Osho, I consider him as a genuine enlightened master.***
