yes. they want to feel their emotions are valid. even if they aren't. Astrology and other theoretical systems also take the locus of control out of their own authority and place it in a higher authority to which they are subjected.
and therein lies the problem. not every emotion is valid. some emotions are invalid. but if you aren't responsible for the causes of your emotions... you're not responsible for figuring out which ones are valid or invalid. they are something that happens to you, not something you control.
and happy well-adjusted folks... learn to figure out which is which, and unhappy folks... can't or won't do this. and a huge part of therapeutic processes is ... learning to identify and assess your own emotional states and whether or not to act on them.
