Loving Kindness is all about treating others, and ourselves, with compassion, kindness, and acceptance. It's not "tolerance" because that implies you simply are putting up with someone else, while (mentally or otherwise) rolling your eyes or gritting your teeth.
It's not about sappy, moon-eyed, fake affection, either. Rather, it's a somewhat radical idea: understanding that everyone, yourself included, is doing the best they can, and everyone has both sorrows and joys to deal with... so why not do our best to accept that no matter who they are, or who we are, we will make mistakes in our choices?
Even though that may sound like a pie-in-the-sky sort of thing, there are definite, scientifically-proven benefits to the individual who practices loving kindness. Quite a few, in fact, and I talk about some of them in this episode.
Also, as a sort of bonus, there is a guided meditation that goes along with this episode, and I encourage you to download it after you listen to the podcast. This guided meditation is designed to help you achieve an attitude of loving kindness.
