Tengkawang, also known as Borneo tallow nut, is a tropical fruit native to Kalimantan. For the Dayak people, the Tengkawang tree is revered as Tree of Life, a symbol of good fortune and harmony with nature. The spiral motif in this design is taken from Pakis (fern) pattern of the Dayak Kenyah tribe in Kalimantan, representing unity and the deep bond among ethnic communities.
