Anyone seen this symbol?

Hi,

Please see the symbol attached in the link. Does anyone know what this symbol could mean?

I was meditating on my heart center for around 15 min. Normally, I see only a black void. But this time, a symbol appeared very clearly. It looked like almond-shaped blue eyes with closed lids. Above them, there was a glimmering shape—orange, green, yellow, and red. Looked like a hieroglyph, symbol or small snakes.

Then I felt intense heat in my heart center, which began to radiate outward. After few seconds, the heat shifted to my belly and also started to radiate.

Then the meditation ended. An ad started playing, and everything vanished.

I tried searching on ChatGPT and Google Images, but found nothing. I’d really appreciate if experienced meditators could comment on that.
