 If grass was thereafter found outside the mouth of Tarn wirrung, it was regarded as evidence that the good spirit "Puit puit chepetch" had conveyed the corpse via the subterranean passage to the island, while guiding its spirit to the realm of the clouds.If the burial coincided with the appearance of a meteor, this was read as proof that the being in transit to the heavens had been furnished with fire.If grass was found at the cave when no one had been buried, then it was thought it showed someone had been murdered, and the cave could not be approached until the grass had been dispersed.
