tṛṇajyotiriti khyātā śṛṇu divyauṣadhī priye
niśāsu prajvalennityaṃ nāhni jvalati pārvati
tasyā mūle tu nikṣiptaṃ kṣīraṃ raktaṃ bhavet priye //

Hear, O beloved, of the divine plant known as tṛṇajyotis: / it constantly blazes at night, it does not burn by day, O Pārvatī; / milk thrown at its root becomes red, O beloved.
