The stream of experiencings that is what living is draws it being from an underlying ground field, in such a way that everything that is most 'real' in that experiencing and which goes through layer after layer of reference and association is ultimately rooted directly in the field. Even if this is a purely intellectual conviction it reorients basic awareness in such a way as to become a imperturbable certainty. And thus the fear of death is strongly mitigated, but only the fear of one's own death. The death of the other, of others, is even more sharply and tragically felt, irrespective of whether you believe them to share the same understanding.
