What is Sanyas?

Renouncement
Correct, but renouncement cannot be a doership.
There is a subtle yet significant difference.
Renouncement should be a result, not a positive action.
(Positive actions are mind-generated).
They should be a result of what?
Result of establishing in the eternal truth (as Priya says).
That way, the focus will be on the eternal truth, and not on what one has to renounce.
Renouncement will happen once the truth is realized; it will be its result.
When the eternal truth is realized, no giving up remains, because Sansar and Sanskaras both were illusions (aabhash – just like the blueness of the sky or the colors of the rainbow).
Sansar and the sanskaras are one package, just as a dream involves physical characters and our emotions about them.
We wake up to the light of awareness, and the dream disappears (because it wasn’t there at all; its existence was only due to our belief in it).
