The sruk is a particular implement for pouring ghee in sacrifices. It is about an arm’s length long and is made of a particular type of wood called vikaṅkata. The sruk has a rodlike handle and a spout with a shallow groove at its tip that resembles a swan’s beak. Its front part is a carved-out spoon the size of a fist. The sruva is another implement used in sacrificial oblations. It is made of khadira wood, is smaller than the sruk and is used to pour ghee into the sruk. It is also sometimes used instead of the sruk to pour ghee directly into the sacrificial fire. These are the Lord’s symbols in Tretā-yuga, when the Lord incarnates to introduce the yuga-dharma of yajña, or sacrifice.
