翻译 - 巴西葡萄牙语-英语 - Água de beber camará Abre todas as portas...

I haven't got a clue what this means and I'm dying to know..Would you translate this text into English? what could this mean?

Complete lyrics of Tom Jobim's song:

"Eu quis amar, mas tive medo
E quis salvar meu coraçao
Mas o amor sabe um segredo
O medo pode matar seu coraçao
Agua de Beber, agua de beber, camara
Agua de beber, agua de beber, camara

Eu nunca fiz coisa táo certa
Entrei pra escola do perdão
A minha casa vive aberta
Abre todas as portas do coraçao
Agua de beber, agua de beber, camara
Agua de beber, agua de beber camara"

"camara" can't be translated since it's a way of addressing people in the region of Bahia/Brazil.
