This is 'Kei', which means 'enlighten' or 'state'. (That's the 'tell someone facts' state, not 'take someone's tax' state.)
The bottom square denotes an opening. The top sort of P-shaped element is one half of an elaborated carved temple gate. If you extended the side bar of the P all the way down to the bottom of the picture to form the arch, the square at the top and the line over it would be the carven temple gate. (The gate radicals are used in many kanji that connotate 'between' concepts). So, the two are a door, an open door.
The crisscrossy radical is an arm holding a sword, and denotes strength/power/force/coercion. Used here as a causative element: to throw open the temple doors. Over time the meaning broadened to just "open up," and eventually the figurative idea of 'enlighten' - to open oneself or someone else up to truth. 'State' is believed to have been associated later, from the idea of explain/inform.
