विषण्णालिकमुभयतोरात्रं यामतूर्यम् ॥ कZ_०२.३६.३४ ॥
viṣaṇṇālikam ubhayato-rātraṃ yāma-tūryam
There shall be a “viṣaṇṇālikā” signal on both nights, and a watch-signal (yāma-tūrya) for each watch-period.
To synchronize patrols, mark watch changes, deter crime through audible presence, and provide citizens predictable cues for curfew/safety routines.
It implies standardized SOPs for urban security—timekeeping, instrumentation, and coordinated manpower deployment.
