Quick Answer
Box Breathing is sama vṛtti pranayama, the classical equal-ratio breath from the Patanjali lineage. Drawn from the Hatha Yoga Pradipika 2.7-2.10 and modernized by Mark Divine, the 4-4-4-4 pattern (inhale, hold, exhale, hold) gives the practice a regulated baseline.
Tradition and source
Tradition
Patanjali pranayama lineage (modern Western adaptation)
Classical source
Sama vṛtti pranayama, "equal-ratio breath", described in Hatha Yoga Pradipika 2.7 to 2.8 lineage
Modern source
Modern adaptation popularised by Mark Divine (former Navy SEAL); validated in stress-research literature
What this practice does
Equal-ratio breath was practised long before it became a Navy SEAL stress-management protocol. The classical name is sama vṛtti pranayama. Use it when you want an even baseline before a stretch of work; do not use it during acute panic, where the holds tend to make things harder rather than easier.
How to practice
The instructions below run 3 to 10 minutes. Read through all the steps before you begin. The practice is not the goal; you are.
Equal-ratio breath is what the name says. The inhale, the hold, the exhale and the empty pause are each given the same length as the others.
The lineage counts them out, but the counting is only a way of keeping them even. Evenness is the whole of the instruction.
Stay with it until the attention has something steady to stand on, then stop.

Crystal companion
In Crystal Cassandra's work, certain stones are the somatic companion to certain practices. The pairing is not magical; it is a steady weight in the palm that becomes part of the noticing.
Lepidolite
Lepidolite is the stone most commonly held during storm-weather practice in modern Western crystal healing. It is a lithium-bearing mica, a fact of geology that has nothing to do with why the tradition reaches for it. What recommends it here is plain and physical: it is soft, flat and pleasant to hold. Many practitioners simply keep it in the hand for the length of the practice.
