Evidence
This page collects every sourced claim on tamhonkhoe.com in two tables: one for science, one for scripture. The two kinds of source are kept apart because they answer different questions.
Labels used on the site:
- [Verified]: based on a source we have opened and read, named alongside.
- [Inference]: drawn from a source, but the source does not say it directly.
- [Expert judgement]: the author's own assessment, without a dedicated study. Claims without a reliable enough source are marked "needs verification" in drafts and do not appear on this page.
Table 1. What science finds
| Claim | Label | Source | Used in |
|---|---|---|---|
| Review of 47 randomised trials, 3,515 people: mindfulness meditation programmes (usually several weeks long) reduce anxiety, depression and pain by small to moderate amounts; strength of evidence "moderate" | [Verified] | Goyal et al. 2014, JAMA Internal Medicine, doi:10.1001/jamainternmed.2013.13018 | Convergence 0 – Week 1, Convergence 1 – Week 11 |
| Same review: no evidence that meditation is better than other active treatments such as medication, exercise or behavioural therapies | [Verified] | Goyal et al. 2014 | Convergence 0 – Week 1 |

| 21 trials of loving-kindness and compassion meditation among employees: less burnout (g = 0.40) and stress (g = 0.54), more self-compassion (g = 0.65); results vary by job and practice | [Verified] | Wang et al. 2024, Stress and Health 40(1), doi:10.1002/smi.3273 | Convergence 1 – Week 7 |
