For one human being to love another human
being: this is perhaps the most difficult task
that has been entrusted to us, the ultimate
task, the final test and proof, the work for
which all other work is merely preparation...
it is a high inducement for the individual to
ripen, to become something in himself
for the sake of another person; it is a great,
demanding claim on him, something that
chooses him and calls him to vast distances...
Rainer Maria Rilke
