The more accurate method is to measure the ghaṭikā by marking the shadow of one ghaṭikā, cast by a gnomon of specified shape that has been set up on a level ground. The perforation in [the bowl of] the ghaṭikā-yantra should be made skilfully according to the period measured by the shadow [i.e., chāyākāla-vaśa].’ [...]”.
