The hosts won the second Test by 135 runs on day five and took an unassailable 2-0 lead in the three-match series.
"It was tough for us in India (in 2015). Personally and as a team we struggled there, and mentally it took a toll on us, even after that series. So the guys were extremely motivated for this series to put that right," said du Plessis in the post-match press conference.
"The previous game we spoke about how Newlands was almost on fast forward mode, so it was an exciting game and this was completely the opposite. It needed a lot of grinding, a lot of hard work and a lot of pushing ourselves for longer and longer and that for me makes this Test match incredibly special.

"The conditions werent the conditions we would have liked, but the conditions were there and we still need to win. And I thought we did brilliantly. There were times when India put us under pressure and every single time we responded by huge character so yes, extremely special this Test match," he added.
"I was very concerned when I got here, leading up to the Test match. It looked not like a Centurion wicket that I know. That is a concern, to be honest. I believe this was an opportunity that we missed. We can blame the groundsman but we also have to blame ourselves.
"We made a process where we make sure Cricket South Africa has someone that looks after the groundsman to get the right kind of pitches when we play against teams. Thats something I will be taking up and making sure we can improve," du Plessis said.
"For me the way to look at that is even the Indian batting line-up struggled in conditions where their spinners were much better than ours. Every Test match lasted three days.
"In this series there have been times when it has looked tough, but there have been guys scoring runs and guys taking wickets, so there is always that battle between bat and ball. If you have that, for me it is a good wicket.
India were bowled out for 151 runs in their 287-run chase with debutant Lungi Ngidi picking up 6-39 and became only the seventh Proteas pacer to pick a five-wicket haul in his maiden Test.
"It speaks volumes for his maturity. When new guys come into the team, from my side its important to make sure they feel like they belong, but then for them to perform means they have good heads on their shoulders and dont see the occasion as too big.
The Indian bowlers had done well on this pitch in restricting South Africa to 335 and 258. Faf praised AB de Villiers for his 80 runs in the second innings, while also talking about Virat Kohlis 153 who was the only Indian batsman to cross 50 in this match.
"The runs he scored in this Test were important but I want to focus on the partnerships. Yes, AB looks like the superstar from an Indian perspective.
"We saw yesterday that we took India so far beyond that point that they just collapsed this morning because the runs were too much.
"Obviously AB is a special player and were very privileged to have him in our team because he has the ability to counterattack. Virat Kohli is similar. They put bowlers under pressure, he said.
"Big time! It was the same when we were playing Australia and we were 4-0 up. Its an amazing opportunity - not a lot of South African teams have had it. It makes us even hungrier to go out there as a team, so were really looking forward to the next Test.
"We havent had the opportunity to beat India 3-0 for a while," du Plessis signed off.
