Actress Jennifer Aniston is toying with the idea of joining Kabbalah and it's all thanks to Demi Moore.

The two recently got together to discuss their romantic comedy `Mean Moms` and Aniston noticed a marked change in her old friend, reports showbizspy.com.

`Jen was struck by how calm and centered Demi seemed. Demi explained that it's a combination of Kundalini yoga, meditation and studying Kabbalah,` said a source.

Aniston has also signed on for Kabbalah lessons, the source reports.

`Kabbalah is a fit for her because it's about 'finding your light' and helping others,` said the source.
