yaścānena mahādevi dve saṃdhye'stamanodaye ..
stautyarkaṃ prayato bhūtvā sarvapāpaiḥ pramucyate ..
sarvakāmasamṛddhātmā sūryalokaṃ sa gacchati .. 23 ..

And whoever, O great goddess, having become pure, praises the Sun with this / at both twilight junctions—at setting and rising—is freed from all sins; / abundant in all desires, he goes to the world of the Sun.
