A sub-ritual for initiating the post transplanting holiday season, ulpi 1a, performed the first evening of the season.
Prayers to numerous spirits are recited. During this ritual the poor do not kill chickens or sacrificial animals in anticipation of sacrificing chickens the following day, pītaw. The rich continue the ritual, killing two or three chickens and the spirits, Būlul, and his wife, Būgan an hi Imbūlul, are called by invitational chanting, baltung 1, to join the festivities.
