Well I'll be honest I'm not familiar with the Egyptian school of symbolism or even thought for that matter, but I have been watching Ancient Aliens and that has familiarized me with the topic. It reminds me of a symbol I was taught that is similar to a steering wheel teaching that God the Father is God, Jesus the Son is God, and the Holy Spirit is God, so they are all God but they are individually separate. It also reminds me of a symbol I was taught in college showing birth>life>reproduce>death>repeat or something along those lines. It's been so long though I can't remember. That's all I got though.
