Dr. Kenneth Ring is one of the founding fathers of near-death experience research. He says:
"It may seem farfetched that near-death studies could make a direct contribution to world peace, but many researchers and scholars have been impressed deeply by the consistent pattern of value changes that near-death survivors express and manifest following a NDE. Recurrently and reliably, they speak of the values of unconditional love and acceptance, human brotherhood, compassion and tolerance, and tend to endorse a spiritual or religious point of view that ignores racial, national, or cultural distinctions."
