Meaning of "as"

Hello everyone

I’d like to ask about the meaning of as in the following context:

You are all light, as we are all light. What this means is that our bodies are electrical in nature, and react as a battery would in a flashlight. When our vibratory rate reaches a certain frequency, it triggers the Light particles or photons in our body to ignite, so to speak, and it turns on the Light in our bodies.

Does “as” mean since (because) in this case?


Thank you very much, Mexicana1000.
