The death of each of us is in the order of things; it follows life as surely as night follows day. We can take the tree of life as a symbol. The human race is the trunk and branches of this tree, and individual men and women are the leaves which appear one season, flourish for a summer and then die. I too am like a leaf on this tree and one day I shall be torn off by a storm, or I shall simply decay and fall and mingle with the earth at its roots. But, while I live I am conscious of the tree's flowing sap and steadfast strength. Deep down in my consciousness is the consciousness of a collective life, a life of which I am a part and to which I make a minute but unique contribution.
When I die and fall, the tree remains nourished to some small degree by my manifestation of life.
Millions of leaves have preceded me and millions will follow me; but the tree itself grows and endures.
