Jennifer Aniston's man, Jim Curtis, says the two have an enlightened way of working through their issues ... dropping down for light meditation after dropping hard truths on one another.

The author and hypnotherapist opened up about his couple's trick with the actress ... telling Jamie Kern Lima on her YouTube show that the pair use meditation to recenter themselves after arguments -- to come at their issue from a less emotional place.

Jim says they also talk a lot through their issues ... and, while they don't use it regularly, he says they have used a four-line refrain -- which goes "I'm sorry. Please forgive me. Thank you. I love you," -- in the past as well.

Jim and Jamie agree ... when people use these techniques, it reinforces the idea that life is too short -- and instantly brings down the convo's temperature.

As you know ... Jennifer and Jim took a trip to Mallorca last summer, which got the rumor mill buzzing that they were more than friends.

They hard-launched the romance on IG in November ... and, though they've remained relatively private, we have seen them take a few romantic vacations over the last few months, too.

So meditation seems to be great for their relationship ... though we're sure the view from a yacht deck doesn't hurt either!
