Comparing MST and TP Question

[MachX]

Ok so I have been playing psu for a little over a week now and I must begin by saying im an avid pso veteran. However I know you know longer use TP to cast spells. So I was wondering, what does MST and TP really means in this game? Unfourtunately I cant seem to find out online and I dont have an instruction manual to look at. Sorry for such a dumb question but I really would like to find out. Thanks in advance.

TP measures how strong your technic attacks will be. The higher your TP the stronger your spells are. MST is a measure of your resistance to technics. Basically, the higher your MST the less damage you take from magic attacks.

TP is technic power, the higher TP the stronger the technics.
MST is mental strength, technic defense.
