go into
Cross the threshold
Go into means to enter—a building, a room, a profession.
You go into medicine or go into business.
The phrase extends to beginning states: go into shock, go into labor, go into effect.
To go into something is also to examine it in detail: I won't go into the reasons why.
When things go into other things, they're absorbed or invested: A lot of effort went into this project.
