Carl Sagan


The significance of our lives and our fragile planet is then determined only by our own wisdom and courage. We are the custodians of life’s meaning. We long for a Parent to care for us, to forgive us our errors, to save us from our childish mistakes. But knowledge is preferable to ignorance. Better by far to embrace the hard truth than a reassuring fable.

If we crave some cosmic purpose, then let us find ourselves a worthy goal.”

Another Tango

I saw the twinkles in your eyes
the flush on your face
and the flame in you heart
when you told me that
something I said got you thinking
thinking about how to make your life better
and how to make yourself better…

You are as good as a good person can be
I just know
But you can always add more fun to your life
give a little more joyful moments to your soul
You are the center of your universe

Keep that fire in your heart going
and never stop it from growing
until you start glowing
in the darkness around you
Like a star,
like a supernova
dancing in the universe
that you are creating for yourself.

I would enjoy watching you
from near
from afar
from within your heart
