" The singer alone does not make a song,
there has to be someone who hears.
One man opens his throat to sing, the other sings in his mind.
Only when waves fall on the shore do they make a harmonious sound;
Only when breezes shake the woods do we hear a rustling in the leaves.
Only from a marriage of two forces does music arise in the world.
Where there is no love, where listeners are dumb, there never can be song. "

― Rabindranath Tagore , Selected Poems
