Sage Art Wood Release: True Several Thousand Hands

The True Several Thousand Hands is a technique which is utilised by both Hashirama Senju and Spiral Zetsu.

Hashirama Senju
After entering Sage Mode, Hashirama creates a wooden statue of titanic proportions, easily able to dwarf a tailed beast like Kurama. Thousands of hands emanate from the statue's back in countless concentric rows, while its two main hands are clasped as if in prayer. The statue can serve a variety of purposes in battle from fighting on Hashirama's behalf, to defending and even using other techniques with it. The sheer size of this technique makes it almost impossible to attack Hashirama, enabling him to remain perfectly still to replenish his senjutsu chakra.

Spiral Zetsu
Spiral Zetsu was shown to also create the wooden statue, albeit at a much smaller scale to Hashirama's during the Fourth Shinobi World War. The statue demonstrated the ability to release streams of the five chakra natures from the small heads encircling the main head of the statue. Each of these five heads used a different nature simultaneously against Allied Shinobi. Due to not having Hashirama's Sage Chakra, Spiral Zetsu's variation is much smaller in comparison.

Influence
This technique seems to be influenced by the Buddhist bodhisattva of compassion, Avalokiteśvara, also known as.

One prominent story tells of Kannon vowing never to rest until he had freed all beings from Saṃsāra. After strenuous effort, but struggling to comprehend the needs of so many who still had yet to be saved, his head splits into eleven pieces. The Buddha Amida, seeing his plight, gives him eleven heads with which to hear the cries of the suffering. Upon hearing and comprehending these cries, Kannon attempted to reach out to all those who needed aid, but found that his two arms shattered into pieces. Once more, Amida comes to his aid and grants him a thousand arms with which to aid the suffering.

Trivia

 * When Hashirama used this technique, the creatures created through the Wood Release: Wood Human Technique and the Wood Release: Wood Dragon Technique sit atop the head of this wooden statue.
