Samadhi
Collectedness. Freedivers know
Samadhi is the state of collectedness in meditation, deepened through the jhanas.
In freediving you catch it when you dive without resisting the water. That’s where a freediver begins.
The other day I remembered: in freediving I had landed in samadhi, and tried to reproduce it in meditation — there’s nothing to do there, just relax completely and switch off. Turned out it’s not that simple. Easier to dive deeper. You are gone, and the sensations are magic.
