sabījā cauṣadhī grāhyā kācid gulmalatā priye
mantrasiṃhāsanī nāma dvitīyā devi khecarī
pātālayantre tattailaṃ gṛhṇīyāttāmrabhājane //

A plant with seeds is to be taken, a certain bushy creeper, O beloved; / the second, O Devī, is named mantrasiṃhāsanī khecarī; / one should collect its oil in a copper vessel using the pātālayantra.
