“So, let this Asian-African Conference be a great success! Make the "Live and let live" principle and the "Unity in Diversity" motto the unifying force which brings us all together-to seek in friendly, uninhibited discussion, ways and means by which each of us can live his own life, and let others live their own lives, in their own way, in harmony, and in peace.”

Variant: Live the beauty or your own reality.

Life Without Principle (1863)
Context: I will not talk about people a thousand miles off, but come as near home as I can. As the time is short, I will leave out all the flattery, and retain all the criticism.
Let us consider the way in which we spend our lives.

"A Creed To Mr. David Lubin", stanza 1, LINCOLN & Other Poems (1901), page 25.
Context: There is a destiny that makes us brothers:
None goes his way alone:
All that we send into the lives of others
Comes back onto our own.

I care not what his temples or his creeds,
One thing holds firm and fast
That into his fateful heap of days and deeds
The soul of man is cast.

Context: We are disposed, somewhat by culture and somewhat by nature, to solve our problems by violence, and even to enjoy doing so. And yet by now all of us must at least have suspected that our right to live, to be free, and to be at peace is not guaranteed by any act of violence. It can be guaranteed only by our willingness that all other persons should live, be free, and be at peace — and by our willingness to use or give our own lives to make that possible.
