"The one who plants trees, knowing that he will never sit in their shade, has at least started to understand the meaning of life". / Rabindranath Tagore
Ovan brukar attribueras ibland ett grekiskt talesätt, som lyder "A society grows great when old men plant trees in whose shade they shall never sit". Men de flesta menar att det är poeten Rabindranath Tagore som uttryckt det.
