[Marvel/DC/Superhero] What is "telekinetic energy"?

When characters use telekinesis, objects move. But when someone like Psylocke creates a "telekinetic blade", what is that? Is it light held together by her telekinesis? Is it some sort mental electricity? What kind of energy is that and where does it come from?

It's force and it comes from their mind.

So telekinesis is just exerting force on an object with your brain.  You move it by basically pushing it around with mental energy.

When people make telekinetic constructs, like Psylocke's blades, they're basically coalescing that force into, essentially, a physical object. (Though keep in mind Betsy's tele*kinetic* weapons are a fairly recent development and early on she used a tele*pathic* blade, that hurt people's minds but didn't cause physical interactions at all.)
