The Bodhisattvas who arose from beneath the ground are none other than ourselves, if we open ourselves up to realizing it. But the realization is not just a mental acceptance of such information. It is deeper. It occurs on a different plane from intellect. In order to be those Bodhisattvas we need to manifest that condition, draw it out of who and what we are in this life. There are not two separate entities, self and Bodhisattva from beneath the earth, however it is up to us to unify them in body and mind, in action and in word.
