aguru joṅgakaṃ kālaṃ kālacitraṃ maṇḍalacitraṃ vā
Aloeswood (aguru) is of the following kinds: joṅgaka; black (kāla); black-mottled (kālacitra); or ring-patterned (maṇḍalacitra).
They allow officials to classify lots consistently by visible markers, supporting standardized pricing, taxation, and fraud detection.
