One of the problems with being a cynic is that, when you’re trying to learn something new, it’s easy to focus on all the things that sound wrong or silly or otherwise questionable and to disregard the entire lesson or experience as a result.

I was sitting in a meditation class recently, for example, when the teacher said something about past or future lives. I don’t even remember what he was talking about -– probably something about karma and our minds -– but it didn’t really matter. My internal alarm bells went off immediately. I thought: “That’s ridiculous. I’m not coming back here.”

The thing is, I know and like this teacher, and I know he’s very good at explaining meditation, its practice and purpose, in an accessible, down-to-earth and engaging way. And I know, from personal experience, plus all the scientific studies backing it up, that meditation can be very helpful. I hadn’t been to that particular meditation center for a while, and I was enjoying being back and laughing along with his painfully accurate descriptions of how absurdly our minds work sometimes, and how they often cause us distress. Until he said the thing about multiple lives. At that point, my internal critic leapt to attention and immediately dismissed the value of whatever it was he was trying to say. I didn’t hear it. And chances are, it was something interesting.

Aware that he was talking to a group of mostly secular Brooklynites like me, the teacher quickly interrupted himself to let people know they didn’t have to believe in past and future lives to learn to meditate or reap its benefits. But I was aware of how easily and quickly my mind was ready to dismiss him and the whole meditation project, simply because the teacher — who was, after all, teaching at a Buddhist meditation center with a big golden Buddha statue behind him — had briefly mentioned something that is a basic tenet of Buddhism.

I’ve written before about how our minds have evolved to focus on the negative aspects of our experience, largely in order to protect us from mortal dangers. The part of the brain that reacts to fear, centered in the amygdala, also steps up when something isn’t physically threatening, but just doesn’t sound quite right. But it’s important to learn to step back a bit, and let the more developed, discerning part of my brain –- centered in the prefrontal cortex -– play its part, too.

I may not believe I’ll have multiple lives to live, although sometimes I wish I did. But I’m capable of distinguishing that piece of the teaching from the larger point, which is that our minds are influenced by all sorts of things –- including past experiences — that we’re often not aware of. Whether it’s something I did in my past life or something my mother said to me in grade school doesn’t really matter. The point is it may or may not be helpful to me, or to anyone else, today. The purpose of meditation is to develop more awareness of what’s going through my mind so I can choose how I want to respond rather than letting unconscious habits choose for me. And one of my habits is letting a cynical mind quash any new ideas that come packaged in or accompanied by something that makes me squirm.

As my positive psychology instructor, Tal Ben Shahar, pointed out in a recent class: “this is not a package deal.” I was in the middle of a week-long immersion for my Positive Psychology certification course, and struggling with some of what at the time seemed like really dumb, pointless exercises. More than once sitting in that lecture hall, I wanted to flee. But it helped me to hear Tal acknowledge that that’s okay. “You’ll hear things here that don’t make sense to you or just sound silly or unconvincing. If you don’t like them, forget about them. Pay attention to what resonates with you, and use it. Leave behind the rest. This is not a package deal.”

It was an important reminder for a skeptic like me. I too easily dismiss things as irrelevant or meaningless because some piece of it doesn’t jibe with me. This aversive reaction may feel immediately comforting, because now I don’t have to bother engaging with new material and can stay safely ensconced in my own cocoon of imagined superiority. But it’s ultimately extremely limiting, and really kind of silly. It’s a bit like dismissing Freud as irrelevant to psychology because I don’t believe in penis envy. But he did develop our modern understanding of the unconscious, which underpins much of our understanding of the human psyche today. So maybe there’s some value in his work after all.

Our culture of cynicism and irony is so focused on mocking and disparaging what we think is wrong that we tend to overlook or outright dismiss ideas that may be really valuable. The criticism might make us sound really clever — especially if we can express it as a witty 140-character commentary on Twitter. But in the process, we may find ourselves flushing a lot of really helpful wisdom down the drain.
