Nyaya - A thing and its altered condition.

उपनयत्रपनयान्धमोर्विकरोतिहिधर्मिनमितिन्यायः

The maxim originates from the fact that a burning fuel when fully burnt down, and fire is extinguished loses its true nature and is reduced to ashes, and is used to signify that a thing ceases to be called as such when it is deprived of its essential properties.
