I can no longer visualise the sun

[Demonic.Owl.]

Hello, I used to be able to visualise the sun on me during meditations but these last days it seem "transparent" what does this mean?
Also my second question is what is the final stage of meditation once we've reached the end of the 40

1. sometimes there are days when you will feel less strong or intense, this is perfectly fine and happens even to advanced practitioners.

2. There is this thing called Aphantasia, search on the forums, high priestess said that there were members with constant difficulty visualizing, and it was resolved by working on the back extension of the 6th chakra. But it's not a condition that is often encountered.

3. It's also okay to "feel" the color and its properties with intent when working with it but try to visualize anyway.
