What holds up when you check

The second issue: five close readings of the Śiva Svarodaya and the nasal cycle, four pieces on how meditation research measures what it claims, and two essays on consciousness and freedom in Kashmir Śaivism.

In this issue

1. Editor's letter The question under every claim Issue two gathers everything published since the first: eleven articles that all, in different ways, ask the same question.
2. Swara The Shiva Svarodaya: What Holds Up, and the Verse That Does Not I have been building a tool from a tantric manual on nasal breathing. The text is a better observer than I expected, and the one verse the whole tool depends on is the one the evidence contradicts.
3. Swara What Shiva Swarodaya Actually Claims About the Hour The text is more specific than most summaries admit, and specificity is what makes it testable. A close reading of the passages on timing, and what would count as evidence either way.
4. Research notes The Nasal Cycle, as Physiology Understands It What has actually been published on the nasal cycle: the range of reported periods, the autonomic evidence, and the size of the studies. Short version — smaller than you'd hope.
5. Swara The Text Names Seven Things to Measure. Four of Them Are Measurements. The Shiva Svarodaya sets out an eightfold scheme for reading the breath. The scheme is better built than I expected. The flaw is not that three of its dimensions are unverifiable — it is that all seven are collapsed into one verdict.
6. Swara What I Left Out of the Swar Yoga Tool, and Why I built a tool from a tantric manual on the breath in the nostrils. Four things the text teaches are not in it. Here is what each one would have required me to assert, and what the evidence actually supports.
7. Claim check Does Slower Breathing Make Meditation Deeper? The advice bundles two claims together. One of them is among the best-evidenced things in the field. The other has barely been tested, because nobody agrees how to measure it.
8. Research notes How to Measure Meditation A new EEG study finds that a month of OM meditation speeds up responses and shifts one brain component — but only under moderate cognitive load. Working out what that actually shows is the whole problem.
9. Research notes What Meditation Researchers Say When They Are Talking to Each Other I spent two days listening to meditation researchers present to other researchers rather than to the public. The register is completely different, and the difference is itself the finding.
10. Claim check Does Forgiveness Change Your Brain? What the Evidence Shows Forgiveness is said to rewire the brain and heal the body. Here is what the trials actually found, and why the brain-imaging part of the story is the weakest.
11. Philosophy Recognition as Liberation Consciousness, freedom and the world in Abhinavagupta's non-dual Śaivism: why the Trika treats the world as the self-display of a free awareness, and liberation as recognising what you already are.
12. Philosophy Did Your Brain Create Consciousness, or Does Consciousness Create Your Brain? The Trika tradition says the brain is something consciousness appears as, not something that produces it. I find the argument serious. I also want to be plain about what neuroscience can and cannot settle here — which is less than either side tends to claim.
