Apple gets metaphysical in the second verse:All my particles disband and disperse
And I'll be back in the pulse
This was inspired by a revelation she had at a meditation retreat she went to in 2010 at the Spirit Rock Meditation Center in Woodacre, California. After days of intense meditation, she felt a throbbing. Surrendering to it, she had a vision of a pulsating space that formed between the other women on the retreat.
"I knew then what life and death was. It's this pulse," she told Vulture
. "We all share it, and it sounds so cheesy. But it wasn't in my head; it was out of it. It was among us all. It was something we were all in together. It was like this place of home, this pulse we would all be in. I felt like I had found it and everything felt so beautiful."
This feeling of enlightenment stayed with her after the retreat, but eventually faded away. In this song, she's trying to recover it by getting "back in the pulse."
