Sleep is not one unbroken block, but a series of four to six waves, each moving through lighter sleep, deep repair and REM dreaming. Brief surfacings between cycles are part of normal sleep architecture, not proof of a bad night. A short breath practice mirrors that rhythm: rising, pausing, settling, and beginning again.

Warm and clear, with an unhurried steadiness — a voice that settles a busy mind without ever rushing it.
