• Tissue is an extended metaphor for life - fragile, vulnerable, all connected
• Valuing the fragile human condition & the inevitability of death
• Tissue may be old & deteriorating, but there is beauty & power in the love & knowledge it holds
• 'Light' is a metaphor for religious or natural power
• If we let the light through, like tissue, we can be enlightened & liberated
• Urges us to consider that things we might see as permanent are not any more so than our own human tissue
