What am I supposedly believing that is false, that is contradicted by science? What specific scientific findings are you implying that I have got wrong?

This is what you said:

"For example, the idea that you and your environment are not separate from each other may be true in some narrow technical sense but it is also very much false in probably more relevant senses."

You're believing that you and your environment are separate based on "relevant" senses. Scientific evidence is irrelevant to your some of your senses, it is technical. If all of your senses were in resonance, including emotional, then there wouldn't be such a thing where scientific evidence is irrelevant in this context.

So your environment and you are not separate. This is a scientific fact. Because it's all a part of your neural activity. Now I am not denying consciousness, qualia or empirical evidence. I'm already taking it as a premise. But you are emotionally attached to the idea that you and environment are separate, that's why you're unable to accept the scientific evidence. However, if you had a scientific mindset, facts would make you accept it. It's not in the way you think right now "It's true in a technical sense, but not for the relevant senses", whereas one part of you accept it but the other, your emotions, do not.

Exactly this is what I am explaining by aligning with reality, you're aligning and letting the evidence in rather than rejecting from preconditioned beliefs. I think you're starting to understand and that you will be stronger because of it. Even if it might seem a little scary at start. Of course we have to investigate it.

There is a narrow technical sense in which my actions are dependent on the gravitational pull of some particular atom in a random star in a distant galaxy. That atom is having a physical effect on me. This is true and indisputable. In a more relevant sense, that atom is not having any effect on me that I should bother with considering. If a magical genie intervened and screened off the gravitational field of that atom, it would change none of my choices in any way that could be observed.

You don't bother considering because it's an analogy in which the hypothetical scenario leads to that conclusion. Do the same with the statements in context, repeat it, is it having any effect on you that you feel that you're not separate from your environment ("Helping others is helping you?") and so on? But of course you have to write down in the same manner, but now not for an analogy.

Then you're jumping forward and making quasi-religious statements about "aligning with reality" and "emotionally submitting" and talking about how your "sense of self disappears". All that stuff is your own unsupported extrapolations. This is the reason you're having trouble communicating here.

Aligning with reality is an emotional heuristic which follows Occam's razor. Emotionally submitting, you already do. That's an example of if you emotionally submit to a heuristic which constantly aligns you to reality and acts as a guide to your decisions. Then if there is evidence, like I've written in the start of the post, you submit yourself to the extent where it's no longer in "a technical sense".
