With paddy being the major sustenance of life among Dayaks, so the first major category comprises the agricultural-related festivals which are dedicated to paddy farming to honour Sempulang Gana who is the deity of agriculture. It is a series of festivals that include Gawai Batu (Whetstone Festival), Gawai Ngalihka Tanah (Soil Ploughing Festival), Gawai Benih (Seed Festival), Gawai Ngemali Umai (Farm Healing Festival), Gawai Matah (Harvest Initiation Festival), and Gawai Basimpan (Paddy Storing Festival). According to Derek Freeman, there are 27 steps of hill paddy farming. One common ritual activity is called "mudas" (making good) any omens found during any farming stages, especially the early bush clearing stage.
