Great topic!
I’ll have to give it some thought to see if I have personal experience that I can share here to add.
About your points, I completely agree about color affecting us. I know that I like wearing certain colors more than others, or that on some days in some moods I want to wear certain colors. One thing I notice about me is that while I love the color red for certain things, like plants, flowers, insects, animals, etc, I can’t stand to see the color red inside a house. I really dislike red paint or red furniture.
And about music, I definitely think that we are drawn to music that matches our brain frequency and chemistry. When I hear certain types of music it makes me feel physically uncomfortable and uneasy, like making my heart rate too fast. This would be music like heavy metal and such. The music that I love listening to, I know is because of how it feels in my brain. Listen to my favorite music always puts me in a biochemically good mood.
And your third point is definitely a great one. My favorite thing from Bruce that he loved to teach is that you should make yourself feel the feeling of love every day, not just for the sake of doing it but to also train your being and make it an easy, natural thing to do so that it alters your overall state of consciousness so that instead of learning to shift there, you’re just living there.
