<li>The content of the book has been input.</li>

<li>B is where the knowledge from the book is integrated with personal experience.
<ul>
<li>Ideally, this is the state one should reach after reading a book.<ul>
<li>However, it is very costly, so it is not commonly done.</li>
<li>In the intellectual production techniques of engineers, this is expressed as &quot;it is good when <a href="/en/the%20knowledge%20in%20the%20book%20connects%20with%20one's%20experience">the knowledge in the book connects with one&#39;s experience</a>.&quot;</li>
</ul>
</li>
<li>How is this ideal state achieved?<ul>
<li>By chance, something read in a book coincidentally becomes &quot;Ah, this is that thing I experienced before!&quot;</li>
<li>The pattern of <a href="/en/delving%20deeper%20until%20you%20understand%20what%20you%20don't%20know">delving deeper until you understand what you don&#39;t know</a></li>
<li>The former is by chance, so only the latter can be achieved through effort.</li>

<li>Since <a href="/en/books%20are%20already%20abstracted%20products">books are already abstracted products</a>, there is no guarantee that they will descend to the level of C, &quot;just one hop away from connecting to concrete experiences.&quot;

Received. Here's a brief summary👇 
- Books are "already abstracted products." To advance understanding, it is necessary to "delve deeper" into abstract words to concrete episodes and connect them with one's experience.
- The basis of correctness is not a "single authority" but a "network of consistency among knowledge." It becomes stronger with multiple points of support.
- The KJ Method is not about "grouping by default." First, create a mesh with relational lines, draw them closer to the density center with short lines, label 2-3 sheets (summarize) → verbalize "insights" through narration.
- "Moving forward = increasing new insights." The evaluation axis is not the appearance but rather "shorter lines with fewer intersections / concretization of labels."
- Beware of over-abstraction (retain the "scent of the soil"). Single-word labels should be elaborated with "Specifically? For example?" to grow roots.

15-minute &quot;Thinking Fireworks&quot; Light (for personal use) 
<ol>
<li>One sheet for the theme (center). </li>
<li>Generate 10–15 associative labels, draw relational lines between two at a time (first lines → proximity). </li>
<li>For long lines with many intersections, move labels to shorten them. </li>
<li>Enclose 2–3 sheets by hand and label (summarize). </li>
<li>Finally, describe &quot;today&#39;s insights&quot; in three lines.</li>
</ol>
Immediate operational rules (minimal set) 
<ul>
<li>Abstract labels are treated as prohibited words: Always elaborate with &quot;What is X specifically?&quot;</li>
<li>Evaluation is based on progress (increments of new lines/labels/narration) rather than appearance.</li>
<li>When in doubt, follow the order of &quot;network → label → narration&quot; (grouping comes later).</li>
</ul>
Next steps (field application) 
<ul>
<li>Tentatively set a schema for selecting relational labels: <code>is-a / part-of / cause-of / example-of / contrast-with / supports</code> (free description in supplementary field).</li>
<li>In study group materials, color-code &quot;derived from papers / author&#39;s considerations&quot; and clearly state sources (sections) and positions in footnotes.</li>
<li>For &quot;hierarchy-first&quot; discussions, first separate hierarchy (is-a) and network (non-hierarchical edges) into different layers before integrating and visualizing to reduce confusion. If necessary, I can provide the above steps as a checklist or Miro/Kozaneba template.</li>
</ul>
