+# Emptiness Graph
+
+**A typed philosophical knowledge graph of Buddhist emptiness teachings**  
+spanning Theravada, Prajnaparamita, Madhyamaka, and Yogacara
+
+[GitHub](https://github.com/joyboseroy/emptiness-graph)
+
+---
+
+## What This Is
+
+This is not a Buddhist chatbot dataset.
+
+It is a **structured philosophical graph** encoding the conceptual architecture
+of *sunyata* (emptiness) across the major Buddhist traditions — from the Pali
+Canon's *anatta* through Nagarjuna's Madhyamaka, Shantideva's dialectics,
+Yogacara's three-natures, and the Prajnaparamita sutras.
+
+The core insight:
+
+> Nagarjuna's arguments are essentially dependency analysis.  
+> A thing exists because of other things.  
+> Remove independent existence.  
+> What remains is a network.
+
+Emptiness (*sunyata*) is not a fact to be retrieved. It is a **relational
+structure** to be traversed. This graph makes that structure explicit and
+queryable.
+
+---
+
+## Quick Start
+
+```python
+from datasets import load_dataset
+import networkx as nx
+
+# load all splits
+ds = load_dataset("joyboseroy/emptiness-graph")
+
+# build the philosophical graph
+G = nx.MultiDiGraph()
+for c in ds["concepts"]:
+    G.add_node(c["id"], kind="concept", **c)
+for t in ds["corpus_manifest"]:
+    G.add_node(t["id"], kind="text", **t)
+for e in ds["edges"]:
+    G.add_edge(e["source"], e["target"], **e)
+
+# what does the Heart Sutra refute?
+for u, v, data in G.edges(data=True):
+    if u == "heart_sutra" and data["relation"] in ("refutes", "deconstructs"):
+        print(f"  {G.nodes[v]['label']} [{data['relation']}]")
+
+# what implies sunyata, from which tradition?
+for u, v, data in G.edges(data=True):
+    if v == "sunyata" and data["relation"] in (
+            "is_identical_to", "is_precursor_of"):
+        print(f"  {G.nodes[u]['label']} --[{data['relation']}] ({data['tradition']})")
+
+# find passages that mention a concept
+passages   = list(ds["passages"])
+pedges     = list(ds["passage_edges"])
+pids = {e["source"] for e in pedges if e["target"] == "emptiness_of_emptiness"}
+for p in passages:
+    if p["id"] in pids:
+        print(f"[{p['text_id']}] {p['text'][:200]}\n")

+## Dataset Splits
+
+| Split | Records | Description |
+|-------|---------|-------------|
+| `concepts` | 25 | Philosophical concept nodes with Sanskrit/Pali/Tibetan terms |
+| `edges` | 38 | Hand-authored typed philosophical relations |
+| `corpus_manifest` | 16 | Source text metadata, translators, ingestion status |
+| `passages` | 1,126 | Text passages from 10 ingested sources |
+| `passage_edges` | 416 | Passage to concept mention links |
+
+---
+
+## Two Layers
+
+**Layer 1 — Philosophical graph (hand-authored)**  
+`concepts`, `edges`, `corpus_manifest` were written by hand one record at a
+time. Every edge has a `notes` field with philosophical commentary explaining
+why the relation exists. This is the primary scholarly contribution.
+
+**Layer 2 — Passage index (automated)**  
+`passages` and `passage_edges` were produced by `build_passage_index.py`
+from 10 source text files. Texts were split into passages and matched against
+manually defined concept keyword lists.
+
+---
+
+## Edge Relation Types (17)
+
+**Ontological:** `negates` · `presupposes` · `implies` · `is_identical_to` ·
+`is_coextensive_with` · `depends_on` · `is_ground_of`
+
+**Logical/Dialectical:** `refutes` · `extends` · `applies_method_of` · `deconstructs`
+
+**Doctrinal:** `tensions_with` · `reframes_as` · `is_conventional_expression_of` ·
+`is_ultimate_level_of` · `is_precursor_of`
+
+**Practice:** `enables` · `is_obstacle_to` · `is_antidote_to`
+

+
+## Concept Nodes (25)
+
+`svabhava` · `sunyata` · `anatta` · `anatta_of_persons` · `anatta_of_dharmas`
+`pratityasamutpada` · `two_truths` · `two_truths_theravada` · `prasanga`
+`dependent_designation` · `emptiness_of_emptiness` · `alayavijnana`
+`three_natures` · `tathagatagarbha` · `five_aggregates` · `twelve_nidanas`
+`dharmadhatu` · `nonduality` · `skillful_means` · `nihilism_extreme`
+`eternalism_extreme` · `abhidharma_realism` · `cittamatra` · `bodhichitta`
+`three_kayas`
+
+---
+
+## Sample Query Results
+
+```
+Heart Sutra deconstructs / refutes:
+  Five Aggregates      [deconstructs]
+  Abhidharma Realism   [refutes]
+
+What implies Sunyata:
+  Pratityasamutpada  --[is_identical_to]  (madhyamaka)
+  Anatta             --[is_precursor_of]  (mahayana)
+
+Doctrinal tensions:
+  Tathagatagarbha  <--> Sunyata
+  Cittamatra       <--> Sunyata
+
+Tradition comparison on Sunyata:
+  Theravada   : Anatta            [is_precursor_of]
+  Madhyamaka  : Pratityasamutpada [is_identical_to]
+  Yogacara    : Three Natures     [reframes_as]
+  Mahayana    : Bodhichitta       [enables]
