So, these are two different things, that I outlined above. Developing a skill is not a siddhi.
Working with an entity needs the skill in the first place, the entity can’t do it for you, so whether you telepathically get the info from an entity as middle man, or directly doesn’t matter that much.
However, nobody meditates to gain siddhis, that’s not the point of that meditation, and you can meditate for 20 years and not get the siddhi you wanted. The abilities are seen more as distractions and the warning is, that if you are meditating to get “power” - you’ll never get it. Because your intention is all wrong to get the ascension anyway.
This is why we work on our skills as a basic part of practice. Again, here’s the link to the astral sense development thread - I don’t give this out for no reason
