Six Paths Ten Tails Coffin Seal (六道十尾柩印, Rikudō Jūbi Kyūin), Kekkei Genkai Ninjutsu used by Obito and Madara. Taking the ten bodies of the tailed beasts into oneself, becoming a jinchuriki and gaining their power. It goes on to say that it's difficult to control the tailed beasts and that this can cause the user to have a psychological collapse, and needs to either have a suitably strong force of will, either inherently or by finding one, in order to gain control. If they do that, they'll obtain the terrifying/astounding power of a "god that shapes the land."
The top caption says that when it seemed that Madara was making Obito use Rinne Rebirth, Obito was actually weaving the sings for the Six Paths Ten Tails Coffin Seal. The middle caption says that the caster condenses and absorbs the ten tailed beasts into himself, awakening ("blossoming") their original power (本来の力, primal power, essential power).
The bottom left caption says, "To acquire the power of the ten tailed beasts is the same as possessing the power of the Sage of Six Paths, so it is accompanied by the same Truthseeker Orbs.
