Sudden urge to worship a deity?

Hi! I am going through a bit of confusion these days. I live a pretty okay life but i’m not content with what I do. To some, I would be called entitled and ungrateful but i’m just not happy with what i’m doing. that’s the context.

These days I am having sudden urge to worship Maa Kaali. I’m not really sure why. I’ve heard one shouldn’t chant her mantra or invoke her in their lives without proper guidance but whenever I see the “roop” of Maa Kali i feel really peaceful. Is there anything I can do? I have a VERY prominent Saturn in my kundli. Thank you in advance!
