I mean, it's talking about people thinking that "energy, frequency and vibration are just mystical nonsense." People don't think that if you talk about an FM station broadcasting on a particular frequency, or about the frequency of light absorbed by particular atomic orbitals. They think that if you're explaining that you've slept much better since you placed jasper and amethyst on the ley lines near your bed to absorb the negative frequencies.

The implication in the meme that anyone who is using these terms cannot be indulging in mystical nonsense, because these terms can also apply to real things. In fact, though, mystic cranks have been coopting scientific terms for ages, and they show no signs of slowing down. It's a real problem that people confuse crap with science.
