The Japanese text of the line Pain said before letting Shinra Tensei destroy Konoha is:

Pain みを companion うがそれに, そのpain みを経験, それのpain みをReceive け入れ, それのpainみをUnderstanding する.

Feel the pain, experience the pain, accept the pain, understand the pain.

It hurts and hurts.

Those who do not know pain do not know what peace is.

Penn, a character in the Japanese comic "Naruto" and its derivative works, was created by Nagato, the leader of the "Akatsuki" organization, with his reincarnation eye ability. Six corpses were created due to Nagato's inability to move. He came out to replace all his actions. The main body is Nagato's close friend Yahiko. His abilities come from Nagato and he has no self-awareness.

Extended information:

The Six Paths of Pain are puppet ninjas transformed from the corpses of six dead people. Each Pain's face and body are plugged with signals that can connect to A black rod that conducts chakra, a nail-shaped chakra receiver, and six Pain abilities to enjoy sight (samsara eye penetration).

Even if the enemy goes around behind one of the Payns, the other Payne will monitor the enemy. Everything the Payne behind him sees is also what the Payne in front sees, and each Payne Endu possesses the ability of the Samsara Eye. His body, Nagato, has a huge amount of chakra and can control six corpses to fight. These are the reasons why Payne is "powerful".

Nagato uses black rods inserted into his body as a chakra receiver to control (spiritual energy). The Chakra Black Rod can also be used as a weapon. By injecting its own chakra, it can play a role in confusing the chakra of the person being penetrated.

The real Nagato is the seventh Pain-Outer Path (Gedō, Outer Path) who controls life and death. He can use all the skills of Pain's Six Paths.

Since the chakra of the Six Paths body that controls Pain is hidden by the black rod, the position of the body is difficult to reverse trace, because Nagato’s feet were exploded by the talismans that Danzo had hidden underground when Yahiko just died. The formation is damaged by the explosion, so it must be moved with the assistance of machinery, but the ninjutsu performed using the seals is not affected.
