Buddhism tells us that for a spiritual practitioner this moment of complete nakedness — the moment of death — is extremely precious. At death, the forces of nature actually help us to appreciate, recognize and grab hold of the innate nature that has always been within us — the Buddha. The moment of death is especially precious if the practitioner is already acquainted with the nature of mind. This is why Buddhists develop the skills and abilities they will need to make the most of the opportunities that death naturally brings, while they are still alive.
