What do all of these have in common? They are completely unnecessary to meditate correctly. In fact, you don't need anything except your body and mind which most of us carry with us at all times. This is the truth, and yet meditation is marketed using this type of imagery. Why? Because it's easy.
You can tell at a glance someone is "meditating" (even though they most likely aren't). The problem is that this approach attempts to represent and idealize an inner experience which must be felt to be understood. It is also profoundly misleading, sets-up unnecessary barriers to practice and coveys the idea that meditation isn't for everyone, especially to those who might benefit the most.
Meditation isn't pretty. On the outside, anyways.
Meditation is ordinary, practical, noisy, thought-filled, interrupted, sporadic, inelegant, non-dogmatic, scientific, approachable, inclusive, versatile and many other things that don't necessarily make for great social media posts or photos in an ad campaign. What does a meditator look like? You. Your cousin. Your grandmother, neighbor, barista, Uber driver, that guy hanging drywall, him, her, yep, that other guy too.
The truth is that meditators are no different than anyone else, save for the fact that they meditate. And meditation needn't be more exotic than sitting in a comfortable chair, feet up, eyes closed for 15-20 minutes, a couple of times a day. Go ahead, slouch your way to enlightenment! If you're a human being, you can do this.
