it is possible to awaken this unique power is by merging and combining the original originators with he or she's chakra which will gradually synchronise with the Ōtsutsuki's or descendant chakra and maturing into its first stage Seikatai -Peace-, periodically causing its wielder painful pulsations in the the body but is able to get use to the pain. Once the final, most painful pulsation has concluded, Seikitai Tensei -Peace- is complete.

but in order to fully achieve complete form of Seikitai Tensei the user must undergo painful experience breaking their limitations and being put under heavy stress needed to be completely depleted and exhausted physically and mentalty for this to actually occur after using the Seikitai Tensei -Peace-.
