Mantra

Mantra is a ability that some who live on Sky Islands may be born with. Whether it can be learned is debateable, but no evidence that it can be exists. It allows the user to detect people at a distance without knowing they are there, making it a excellent skill for planning battles with. A fully trained user can predict a persons movements as well as their feelings. However, a user with this ability cannot detect a person inside something.

The ability is also enhanced when combined with the Devil Fruit 'Goro Goro no Mi' as displayed by Eneru.

It frist appeared in Chapter 246, Satori used it when Sanji, Luffy and Usopp went throught the Ordeals of Spheres. Aisa was the only known Shandian was born with it and served as plot point when she helps Luffy locate Eneru.

Eneru's mantra was the strongest, although the mantra in each priest and Eneru was displayed in differant fashion. Satori was the weakest, proven that he could not tell Luffy was behind him.
