Something moves forward until it finds a limit — like a body that reaches a wall and stops exactly there, at the point of contact.

There is no break or failure.
There is encounter

Symbolic formation

• tã → advance to a limit
• can → impact stable, closing

👉 tãcã = the movement that reaches the limit and resolves itself in contact
