Will Materialisation

This is an ability that allows the user to manifest and materialise their "will" for different purposes.

Background
This ability was first used by Kaguya Ōtsutsuki in manifesting the Ten-Tails by incarnating herself with the Shinju. Upon being sealed by her two sons, she formulated a plan that would result in her eventual resurrection. This led to the creation of the sentient-being Black Zetsu who, as an extension of her will, would enact this plan.

Kaguya Ōtsutsuki
In order to ensure that her ends are met, Kaguya could use this ability to create sentient life, as she did with Black Zetsu and the Ten-Tails before him.

Karura
After her death, Karura's will inhabited her youngest son Gaara's sand, causing it to automatically protect him whenever he is in danger.

Black Zetsu
Like its creator, Black Zetsu was also able to use this technique to subtly influence the thoughts of others, or forcibly make them do his bidding by directly channeling his will through them.

Madara Uchiha
Madara was able to use a variation of this technique that is instead be channelled through chakra receivers. He was not only able to remotely manipulate the actions of those embedded with the rods, but also manipulate the receivers imbued with his will telekinetically.
