I used to take an advanced course, in the early 80's, with Marion March, a double Aquarian, old school astrologer. She titled her books 'the only way to learn____' ---so you get an idea how fixed she could be. lol
She would get very mad at me for drawing in those 'silly' colored lines on my charts I used in class. She'd say 'there is NO NEED for that mess, cluttering up the center of your chart'
By the end of our long semester, and after seeing all of her younger students doing it, she actually began appreciating it and eventually had her computerized printouts add the aspects. Originally she didn't. And some of us colored them in when we were preparing our homework. lol
