Application: interior / symbolism.
Trebnitza - a specially allotted place in the house where the gods (idols) are granted bloodless rites. Placed in front of the red circle of the gods. Grain is poured into trebnitza (wheat, barley, cereal, etc.), and also a candle supplied to the ritual. Vedic trebnitza serves as a home altar, so it is a holy place. It is necessarily to pour rites with a pure heart when you communicate with Gods.
