What is the target of the Telekinesis spell?

ITL 27: "the object manipulated" ... "the wizard has one “invisible body”"

So is Telekinesis a thrown spell that targets one object or is it actually a creation spell that creates an invisible body that can then pick up and throw any number of objects?

[Shostak]

It is clearly listed as a Thrown spell, the effect of which is a telekinetic force equivalent to an invisible body with ST identical to the caster's.

The "invisible body" is just a metaphor to convey an idea of what exactly your TK can do. It's a relatively coarse and limited ability to move matter, roughly equivalent to what you could do if you were actually standing there, invisible, and touching the thing you're trying to affect.

Some people try to argue that TK is an arbitrary remote matter editing tool - crush hearts without affecting (or having to affect) the surface, pull out all the oxygen atoms from your lungs, etc. The "invisible body" is trying to point out that you don't get super-senses, inhuman precision, Mechanician talent, and so on. Just because a player can describe an effect as moving some object or objects around and rearranging them doesn't mean that effect can be achieved with TK.

The target is the usual one object. If the spell had been meant to create an actual invisible body that you could move around, it would have said so. If that's actually what you want, Summon Myrmidon and throw Invisibility on it. (Feel free to dust off ancient philosophical puzzles like "is a double-handful of water one object" when you feel there's just not enough argument at your table to be having fun, if that's your idea of fun.)

If you want to change objects, re-cast the spell. (The "invisible body" doesn't have to walk or run to the next location. It doesn't actually exist. If you like to think in this metaphor, the body disappears and reappears at a new location when you recast / choose a different objects to affect.
