In an effort to compliment the beneficial changes he's made to his physical well-being, former President Bill Clinton is addressing his inner mental health as well.

RadarOnline recently reported that 66-year-old is taking private classes from a Buddhist monk to better relax his mind and body and reduce stress. In 2010, after suffering various health scares and heart surgeries, Clinton shifted to a plant-based diet, dropping 24 pounds and crediting the change with saving his life.

"When I had my second heart incident [in 2010] and I had the stents put in, I had passed all my physicals, I was doing great, but I was still building up plaque in my arteries," he told CNN. "So I decided that I wanted to see if I could live to be a grandfather, so I just went all the way."

A source told Radar that Clinton's move towards meditation is yet another way he's improving his overall health.

“He has a hectic life, he travels a lot on business as an ambassador for the U.S. and needs something to keep him sane.

“Meditation offers him that, he has a mantra that he likes to chant, and after every session he feels transformed and full of positive energy. It’s definitely doing him the world of good — he feels fitter and stronger than ever,” the source added.

According to WebMD, studies have shown that meditation not only lowers blood pressure but also can strengthen your immune system.
