pādena vā krīḍamānā jalaṃ lipsaṃti ye narā ..
teṣāmapi śrāddhaphalaṃ vidhivatsaṃbhaviṣyati ..
tatra liṃgāni pūjyāni śūlabhedādikāni tu .. 28 ..

Or men who, playing about, touch the water with their foot, / to them also shall accrue the fruit of a śrāddha performed according to rule. / The liṅgas there, such as Śūlabheda and the others, are to be worshipped;
