I got the same HPS RX card as advice in regards on how to approach a certain relationship and based on what I read from that post, I read it to mean to retreat and go within and focus on gaining more knowledge until the right time presents itself.
Well, first off, and as always, if you're getting a really strong vibe that this is what the card means, then that's probably what the card means. My main problem with the interpretation of the HPS rx here as gossip, slander, misunderstanding is that it doesn't relate to the question asked. If the question had been "what's going to happen with this project..." then, given the situation with the company, that would have been a reasonable interpretation. But if one is saying, "I've got to work on this creative project, what advice do you have for me..." well...why would slander, gossip or selling out secrets enter into it?
As Barleywine so vividly pointed out, our HPS rx CAN indicate secrets getting out. But does that relate to this question? If not, then worries and thoughts about such issues may be hijacking the reader's understanding of what the card is really saying.
rx cards in the advice position: rx cards in this position are tricky. If you get them as an "Outcome" then you can say "This will be blocked." So in the case of HPS rx as outcome, you might say, "Your not going to get to retreat, or keep this secret, or feel like your intuition is working..." But in the advice position, you have a quandary. HPS rx--"don't retreat into solitude"...well, what does that mean? To be social? If so, why not a card that says "be social" like the 3/Cups? Go out into the world? Why not the "World" card? Use logic rather than intuition? Why not the Sun or the Queen/Swords?
Perhaps the best way to read rx cards as advice is as kind of a "This is a bad idea right now." HPS upright, you'd retreat and stay quiet and secretive and give yourself time to ponder the situation. This is a good idea. HPS rx says "that's unadvisable right now." It doesn't tell you what to do so much as to reconsider what you may be thinking of doing. And this relates back into the "turning right-side-up" advice that started this. If you want to retreat and think, and the cards are saying "that's unadvisable," then you need to either ask "why not?" and put down a card, or if you know, avoid it till it is advisable. Until you've turned the card around.
How would this work in a relationship? Well maybe if you retreat and go silent, the person will feel hurt, like you're giving them the silent treatment. But you may really feel like not talking to them. You may really want to retreat. So, you need to say to the person, "I really need some quiet time to figure out how to express my feeling and help us through this." You turn the HPS right-side-up, you make sure they won't misunderstand your silence, and thus, you get rid of that block so you can do as needed.
This is not, and can't be, the only way to read rx cards in that position, because, of course, different rx cards have very different meanings. But it's certainly one way.
