Nelson Mandela once said 'If you speak to a man in a language he understands it goes to his head..?

Question

if you speak to him in his language it goes to his heart.'

Does anybody know the origin of this quote? When and where it was said?

Answer 1

South Africa

Answer 2

I tried searching for the source.. but most sites are only quoting him... what I found was that he was asked about his passion for learning Afrikaans while he was in prison and then that was his response.

It's at the end of the site I put below.
