In the science of svarodaya, the breath is an oracle. The Śakunaśabdapraśasti — a compendium that shares the Narapati lineage of vowel divination — reads which nostril the breath is flowing through, and which syllable is rising, to answer the questions people actually brought: Will the sick recover? Which army wins? Is it safe to travel? Will a child be born?
Two currents, two answers
The text names the two channels of breath — the lunar current and the solar current — and assigns each its use.
In exhaustion, grief, fasting, fever, or even fainting, one should flow the lunar current for the purpose of restoring consciousness to one who has lost it. The messenger stationed in the left upward path should be known; this is the left. The right is considered to be located in the solar current.
Which current is flowing at the moment of a question changes the meaning of everything that follows — and the text even reads a messenger's success or failure from the state of the breath when they arrive.
Every act has its syllable
Like the wider Narapati tradition, the compendium schedules human action by the rising syllable — fierce acts for the fierce sound, gentle acts for the gentle one.
All auspicious and inauspicious acts should be performed according to the strength of vowels and colors. Killing, delusion, paralysis, enmity, expulsion, and subjugation — one should perform these at the rise of Guhasvara (hidden sound). Bathing, drinking, and all such acts, as well as clothes, ornaments, and decorations — the commencement of learning and marriage should be performed at the rise of Jivasvara (vital sound).
A science for every question
The Śakunaśabdapraśasti turns the body's own rhythms into a system of answers. The breath is always moving, always in one current or the other, so the oracle is never closed — a question at any moment can be read. That, more than any particular prediction, is the genius of svarodaya: it made divination continuous with life, available on demand, written into the ordinary act of breathing.
