"We can't stress how important the Lions is for players - it is the absolute pinnacle of our careers".
"The Tullow Tank" has been cleared of any wrong doing, his citing has been dismissed and he will be available for the third Test match of the series.
The Lions will have Sean O'Brien, who is free to play after escaping a ban having being cited for an alleged swinging arm to the head of Waisake Naholo, and Gatland feels the Lions now have some genuine momentum.
And Lions head coach Warren Gatland added: "We would like to thank the panel for their professional and diligent approach".
Williams was sent for an early shower in the 25th minute after a crunching shoulder charge that struck Lions winger Anthony Watson flush in the face.
"We know historically when New Zealand teams lose they respond and there's no better example of that than what happened in Chicago a year ago and then in Dublin in the following game", he said.
"It's great that we managed to put that performance into the jersey and, hopefully, that will keep the Lions going for at least another four years".
He said: "I'm a pretty happy clown this week". He converted seven of them.

The Lions were nearly hamstrung by conceding 13 penalties at the Westpac Stadium though, leaving assistant coach Rowntree to predict a lengthy inquest on discipline in the build-up to Saturday's series decider in Auckland.
"Obviously I'm really disappointed but happy to be able to get in there and say my piece", Williams said afterwards. "We couldn't live with ourselves if we did that", Rowntree said as the Lions headed for four days recovery at New Zealand's adventure capital of Queenstown.
"We'll have to be prepared for a tougher encounter next week, we'll be against 15 blokes most likely and have to step it up again".
"Silly penalties made it hard for us chasing the game a bit too much, but I thought we attacked them and you need to do that".
"The All Blacks were very effective in the third quarter and squeezed penalties out of us. Nobody gave us a chance, and as long as the mental capacity of the lads within our group, players, management, staff, we all rub off on each other positively and believe we can beat these boys and we genuinely do". "We'll talk to the medics and the conditioners and then start thinking about the team".
