In this connection some say: ‘The Ghaṭikā-yantra is a vessel [made out] of one of the metals like gold, silver or copper, hemispherical in shape [i.e., ardhavṛtta-ākāra] (lit. semicircular), which holds (dhāraka) sixty palas of water and which is filled with or discharges [the same amount of water]’ [...]”.
