शुभगो यद्भगस्तद्भिस्न्वादिस्थेन तद्धिकृत् । प्रोक्तेतरस्थानगतस्तत्तद्भावक्षयं करः ॥ १४३ ॥

When the form “śubhaga” (auspicious) is used, it denotes “one who possesses good fortune.” But when that same element is used with an affix of the snvādi group, it becomes an agent-form meaning “one who brings about that result.” And when a stated term is placed in another syntactic position, it conveys the diminution or destruction of that very state.

Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It teaches that meaning is not fixed merely by a word’s surface form; context and grammatical formation determine sense—an important discipline for correctly understanding dharma and moksha teachings.
Indirectly: it safeguards bhakti and moksha teachings by insisting on precise interpretation—misreading terms can distort doctrines about devotion, merit, and liberation.
Vedanga Vyākaraṇa/Nirukta: the verse illustrates how affixes (like those in the snvādi group) and syntactic placement shift a term from ‘possessing fortune’ to ‘causing/producing an effect,’ or even to a sense of loss/diminution.
