(In general) I would say it depends on why you're studying it and how strong your faith is.
I've studied it because I was exposed to occult-type practices as a child, but put it out of my mind as an adult until my husband passed away. After that, I found occult-type drawings among my husband's things. Then the house became "haunted" (like something out of the Amityville Horror movie).
I, myself, wanted to avoid EVER having to deal with that type of situation again. So, I studied up on it to see the 'warning signs' of people who might be involved in it. I'll never believe in it or want to practice it, but I wanted to be able to understand it enough to recognize it when I see it.
When I was married to my husband (and living in our first house), I would see these tables he had in the attic with candles on it in a semi-circle. (With ceramic skulls among them.) He had drawings of demons all over the room there. (They looked like angels, but with bat-type wings.) At the time, I thought they were pictures of angels and my husband explained everything away. Back then, I believed him. It wasn't until after his death, that I found his clearly identifiable pictures of Satan. (My hair stood on end the day I found that!) My husband attended a Catholic church and denied any interest in the occult, so there was no way to easily tell what he believed in. I study the occult sometimes so I'll know it when I see it. I felt like I was hoodwinked by my husband and want to avoid that happening again.
As for the poster--if you or your husband are studying it because it sounds cool and you're curious, I'd not study the occult at this time. Your faith may not be strong enough right now to handle some of the things you'll encounter among your studies. When my old (2nd) house was haunted, I was attacked by these bugs that came up out of the floor and covered me like a bee keeper. There was a green glow in the room my husband's drawings were in. When I found the drawings of Satan and threw them out--the green mist and bugs were instantly gone. I prayed the Our Father the entire time I was in that room. Lights were flickering, I'm walking among this mist, there are bugs crawling all over me--if my faith had not be strong at that time, I may have completely freaked out. (And there's still a lingering effect going on with me now because of this.)
I, myself, would focus on your RICA for now. You don't know what can of worms you might open by reading about the occult at this time.
