According to materialistic science, any memory requires a material substrate, such as the neuronal network in the brain or the DNA molecules of the genes.

In some instances, the accuracy of past-life memories can be objectively verified, sometimes with remarkable detail.

For any culture which is primarily concerned with meaning, the study of death - the only certainty that life holds for us - must be central, for an understanding of death is the key to liberation in life.
