14.38.16

vratavyājena rājendra na tu gaurī vyajānata ..
kasyacittvatha kālasya nārado bhagavānmuniḥ ..
kaivalyajñānasaṃpannastatrāyātaḥ paribhraman .. 16 ..

under the pretext of the observance, O king of kings, and Gaurī did not know. / Then, after some time, the blessed sage Nārada, / endowed with knowledge leading to isolation, arrived there wandering about. (16)
