Psychic development is a mental skill. You can turn it into something spiritual if you'd like, but it really has nothing to do with the control structure of organized religion.
When you get the limiting beliefs out of the way (including those installed by organized religion), it's easier to develop your psychic senses to the point where they can be quite useful and practical. In this podcast I mentioned how developing my intuitive abilities has helped me tremendously in business over the years. For making big decisions I probably rely on my intuitive sense more than my eyes and ears. This includes picking up impressions on how a particular line of action is likely to pan out. Although I didn't mention this in the podcast, I call it "reading the timestream."
The best teacher is personal experience. I don't need faith to rely on my intuitive senses any more than I need faith to trust my eyes and ears. The tricky part is learning how to interpret those impressions, just as we must learn to interpret sounds as language or visual data as objects. It just takes practice to make sense of the stream of information that comes through.
Developing your psychic abilities is like adding a whole other sensory input channel. It can cut years off your learning curve and help you avoid many problems.
IMO psychic development is the same thing as learning to identify sights, sounds, smells, and textures. The input channel is there, but you have to put in the practice to make sense of the raw data. Otherwise all you can perceive is noise.
