Earth promotes metal - Metal controls wood
In Traditional Chinese medicine Metal (lung and large intestine) is yin in character, its motion is inwards and its energy is contracting. It is associated with the west.

In this video the two characters journey together in a neverending cyclical path.

The movement is influenced by Butoh, a practice that among many things can be viewed as a turn away from the Western styles of dance, ballet and modern, to create an aesthetic that embraces an earthbound physique and natural movements.

Toi-kai-rākau is a house at Waikirikiri marae in Rūātoki. It was built in 1930 and the house is named after an ancestor of the tribes of Te Urewera, Toi-kai-rākau (ko Toitehuatahi, ko Toi rānei).

These tribes were living in Te Urewera before the arrival of the Mataatua waka, and known collectively as Te Tini o Toi.

He is usually called Toi, but his name before he came to Aotearoa was Toi-te-huatahi. His full Aotearoa name was Toi-kai-rakau (usually rendered Toi the wood-eater), so called because he and his people in New Zealand lived on forest products more than on cultivated foods, such as kumara and taro. His history has been gradually drawn out of the mists that first surrounded it. He is Nancy’s tupuna.

Watching the video I was drawn to the idea of Tāne Mahuta and particularly Rangahore who was a goddess. They procreated and she gave birth to a stone. Looking up some other info, there’s a really interesting version where Tāne who wants to take Papatuanuku his mother, as his wife and then she says no, and he literally roots with everything to create the world.

I found this info below that was related to the goddess of Toetoe and Harakeke. The grasses in your video and their entry into the earth were very evocative. Some time after separating earth and sky Tāne desired to have his mother Papa for his wife. But Papa said, “Do not turn your inclination towards me, for evil will come to you. Go to your ancestor Mumuhango.” So Tane took Mumuhango to wife, who brought forth the Totara tree.

Tane returned to his mother dissatisfied, and his mother said, “Go to your ancestor Hine-tu-a-maunga (the mountain maid).” So Tane took Hine-tu-a-maunga to wife, who conceived, but did not bring forth a child. Her offspring was the rusty water of mountains, and the monster reptiles common to mountains.

Tane was displeased, and returned to his mother. Papa said to him “Go to your ancestor Rangahore.” So Tane went, and took that female for a wife, who brought forth stone. This greatly displeased Tane, who again went back to Papa. Then Papa said “Go to your ancestor Ngaore (the tender one).” Tane took Ngaore to wife. And Ngaore gave birth to the toetoe (a species of rush-like grass). Tane returned to his mother in displeasure. She next advised him, “Go to your ancestor Pakoti.” Tane did as he was bid, but Pakoti only brought forth harakeke (phormium tenax). Tane had a great many other wives at his mother’s bidding, but none of them pleased him, and his heart was greatly troubled, because no child was born to give birth to Man; so he thus addressed his mother—“Old lady, there will never be any progeny for me.” Thereupon Papa said, “Go to your ancestor, Ocean, who is grumbling there in the distance.
