According to Osho, a newborn has a fresh brain (a biocomputer) but not a fresh mind. The mind is a nonmaterial accumulation of conditionings—layered ‘manas’ or chittam—clinging to consciousness across lives. When the body dies, the brain ends but these subtle layers persist, producing latent tendencies and potential past-life recall. Discontinuity of memory arises because the new brain lacks prior imprints; enlightenment is the dropping of all layers, leaving naked consciousness.
Your body gets a new computer each life, but the old software of habits and impressions rides along until you erase it.
