BOSTON — Ignorance ran amok in the Boston Bruins’ dressing room, late Monday night.

And oh, how blissful it was.

For example, Zdeno Chara claimed not to know who got the goals for his Bruins’ team. Just that they got enough of them. Milan Lucic said he didn’t know for sure that the decisive Game 6

against the Buffalo Sabres was officially over and done with. He had to take the frenzied TD Garden crowd’s word for it.

That the best of seven Eastern Conference semifinal was indeed over, and that the Bruins, seeded sixth, had toppled No. 3 Buffalo, 4-3.

And none of them knew, even now, who the B’s will play in Round 2, be it Philadelphia or be it Pittsburgh.

They just know they’ve gotten themselves there.

“It was good that we came out and got the win,” said defenseman Dennis Wideman, and now we are moving onto the next series and start it all over again.”

Whom the Bruins will face next is an open question, and completely out of the club’s control.

If top seed Washington is upset by No. 8 Montreal in Game 7 of their series, Boston will face No. 7 seeds the Philadelphia Flyers.

Otherwise, they’ll face defending Stanley Cup champions the Pittsburgh Penguins.

“Yeah,” said center David Krejci, who scored twice for Boston (“Z”, take note). “We  knew we always had it in us and some guys had a tough year, but we knew it was in us and I think we showed it in the first round, but you know, it starts right now and we got to do the same thing in the second [round].”

Krejci sent the sellout crowd of 17,565 into a tizzy when he scored on the Bruins’ first power play of the game, putting Boston ahead, 1-0 at the 13:39 mark.

He was stationed in the slot where he re-routed Mark Recchi’s drive from near the right boards past Sabres’ goalie Ryan Miller.

It was the first time the B’s had scored the first goal of a game the entire series.

“That’s what we wanted to do for all the first five games,” said Krejci, “and [it] didn’t happen. It happened today. It was huge, to play with the lead the whole game, and it’s much more fun when you have a lead, you know, so I think we controlled it pretty good and we didn’t sit back.”

Krejci returned the favor in the opening minute of the second period, while the Bruins were skating 4-on-3.

Manning the left point, Krejci spotted Recchi hovering near the right post and hit him with a pinpoint back door pass.

Recchi, a veteran of 22 seasons, promptly parked his 53rd career playoff goal to make it 2-0.

Buffalo replied at 6:34, after Adam Mair seized on a blind turnover by Wideman, and began a tic-tac-toe play through Tim Kennedy that was polished off by Patrick Kaleta.

However, the best Buffalo could do after that was swap tallies with the Western Conference champions.

Nathan Gerbe, the erstwhile Portland Pirate, did score at 7:40 of the third to bring Buffalo to within 3-2.

However, Miroslav Satan, the former Sabre whose double-overtime game-winner last Wednesday’s helped put Buffalo in the biggest bind, struck for what held up as the game-winner at 14:49.

By that time the overjoyed throng had broken into a chorus of “Shippin’ Up to Boston”, while the Sabres had all but “Shuffled off to Buffalo”.
