Germany coach Joachim Loew says his team's clinical response to Brazilian emotion laid the foundation of their stunning 7-1 victory.
Brazil had gone into the match amid a mood of feverish national expectation and strident rallying cries to win for injured striker Neymar.
A hair-raising rendition of the Brazilian national anthem saw skipper David Luiz holding Neymar's No 10 shirt aloft in a gesture of support.
But Germany met the raw emotion head on and when the opportunities arose, they struck.
"It was important to meet this passion and these emotions with calm, courage and with our own strength," said Loew whose side will now meet Argentina or the Netherlands in Sunday's final in Rio de Janeiro.
The game was won in an extraordinary burst which saw Germany rattle in four goals in six minutes midway through the first half.
Loew said Germany had exploited the chaos in the Brazilian defence mercilessly.
"They were shocked by our goals and it made the game easier for us.
"Everyone did their jobs incredibly well and with total concentration.
"We played well going forward and combined superbly."
But Loew said the Germans must stay humble despite inflicting a record international defeat on the hosts. "A bit of humility would also be very good and we need to be careful that we stay focused on Sunday," said the 54-year-old.
"I knew before the game that if we were courageous, we could win, but no one imagined it would be 7-1.
"After we went 2-0 up, they were disorganised and we took advantage.
"There's no euphoria in the dressing room, we are very happy, but we are not getting carried away.
"After halftime they showed a reaction to try and please their fans in the stadium, but we still controlled the match."
Loew said Germany fans should not expect the same sort of massive result in the Maracana final.
"Nobody should feel invincible. That is perfectly clear and both Argentina and Holland have played a great World Cup so far," insisted Loew.
"Argentina have a very strong defence and (Lionel) Messi, (Gonzalo) Higuain and the others are a fantastic attack.
"(Netherland's Robin) Van Persie, (Arjen) Robben, (Wesley) Sneijder are players that at any moment can decide the match. The final won't be the same as today."
The Germany boss also said he had sympathy for Brazil coach Felipe Scolari and the Selecao having also tasted semifinal defeat as the hosts of the 2006 World Cup.
Loew was assistant coach when Germany suffered a 2-0 extra-time defeat to Italy in their semifinal on home soil eight years ago.
"I remember losing against Italy to a goal in the 119th minute so we know how Scolari, the players and the Brazilian people feel," said Loew.
"I remember 2006 in our own country, how much we wanted to make the final and that's an enormous disappointment for any county.
"I believe this defeat will be difficult to digest for Brazil.
"Until today, Brazil have had a great World Cup, especially as hosts.
"Their passion for football and their people have been great, but, of course, it will be a difficult defeat to accept."
