Dreaming of Dante

How do we determine objectivity of the spiritual experiences of unity or oneness reported by people in meditative state? Neuroimaging research shows that deep contemplative or spiritual experiences alter the brain activity in measurable ways.

In particular, the brain region involved in spatial awareness and in our sense of self, shows decreased activity. When this region quiets, the usual boundaries that define us – and our separateness from the surrounding world, begin to dissipate.

Our brain normally relies on this region to orient us in the physical space and to maintain a clear distinction between ourselves and the external environment. When this activity diminishes, that boundary can temporarily disappear, giving rise to a profound feeling of transcendent unity with something larger than oneself.

Consider this in the context of Dante’s journey. When the Pilgrim reaches the summit of the mountain, he encounters Beatrice—his higher self—and experiences a mystical union that transcends his ordinary identity.

Empirical research shows us that the human brain possesses innate capacity to enter metaphysical states of oneness. In this sense, modern science has caught up with, and has empirically validated, the mystical experiences which sages, poets, and philosophers have described for millennia.
