"Our deepest fear is not that we are inadequate. Our deepest fear is
that we are powerful beyond measure. It is our light, not our darkness
that most frightens us. We ask ourselves, Who am I to be brilliant,
gorgeous, talented, fabulous? Actually, who are you not to
be? You are a child of God. Your playing small does not serve the
world. There is nothing enlightened about shrinking so that other
people won’t feel insecure around you. We are all meant to shine, as
children do. We were born to make manifest the glory of God that is
within us. It’s not just in some of us; it’s in everyone. And as we let
our own light shine, we unconsciously give other people permission to
do the same. As we are liberated from our own fear, our presence
automatically liberates others."

I have taken this from the following post about the common mistake made giving credit for this quote to Nelson Mandela. He did use it as part of his Inaguration Speech in 1994. Read below and also check out the site.

Note About Nelson Mandela

This quote is often found on the Internet incorrectly credited to Nelson Mandela
from his Inauguration Speech, 1994, especially the last sentence of
that quote, “As we are liberated from our own fear, our presence
automatically liberates others.”

For reference, here are links to two official African government sites with Nelson Mandela’s 1994 Inauguration Speech:

• Mandela: Inauguration Address – Cape Town, 09 May 1994, via South Africa Government Online Official Web site.
• Statement
  Of The President Of The African National Congress Nelson Rolihlahla
  Mandela At His Inauguration As President Of The Democratic Republic Of
  South Africa Union Buildings – Pretoria, 10 May 1994, via ANC’s (African National Congress) Official Web site.

I made a post about this awhile back but I can’t find it now. Hmmm. Well I’ve made updates so it doesn’t appear anymore. I’ll make another post with this then.
