brahmeśvare māsikaṃ syāt vyāghrapuryāṃ tu vāsaram
aghoreśe māsikaṃ tu siṃhadvīpe tathā punaḥ
dinamekaṃ brahmagirau vindhye tu kṣaṇavedhakam //

at Brahmeśvara it takes a month, but in Vyāghrapurī a day; / at Aghoreśa, however, it takes a month, and likewise in Siṃhadvīpa; / a single day on Brahmagiri, but on the Vindhya it transmutes in an instant;
