JKW said, something like this:
i am in the habit of not catching all the seeds when squeezing juice from citrus. i believe pulling a lemon seed from your lips, puts you in closer proximity to your food. it reminds me that i'm enjoying what's in my mouth. its a reminder that lemon is part of a tree. and that makes me happy.
the other day, i caught one of my lemon seeds, when i was having a soft drink. i pulled the seed from my lips, felt gratitude and, the seed flew away! it was a fly. that revolted me.
it changed my habit and i now remove all the seeds when i juice.
