Just dotting a few i's... 
"Lautering" (from German: "abläutern") is the separation of wort from the grist.
Since you use a bag or a mesh basket to hold the grist, just lifting it out after the mash leaves (sweet) wort behind in your kettle. The process of just lifting the bag (or basket) out of the kettle and letting it drip out is lautering.
There's also "vorlaufing" (from German: "vorlauf") which is recirculating wort through the grain bed for it to settle, becoming a natural filter/sieve to hold back grain dust and bits, to drain off (lauter) a clearer wort.
Sparging is rinsing/washing, basically. To collect more sweet wort from your grist, boosting mash and thus brewhouse efficiency.

I think you mean "no sparging."
