Difference between obsession and absorption

Absorption means a state of being completely engrossed in something.

An obsession means being continually preoccupied with something.

In context to someone's working habit do they both mean same?

Thanks

The words "obsess" and "absorb" generally have different instigators for the direction of action

The television absorbed my attention.
I was obsessed over the television.

However, both words are perfectly capable of similar intransitive constructions.

I was absorbed by the television.

In that case, the two are generally defined by the level of conscious decision and severity. Someone chooses to be "obsessed", but often has less control over being "absorbed". "Obsession" is normally all-encompassing.

Karen was absorbed with her work and didn't notice Mark until he cleared his throat.
Karen was obsessed with her work, neglecting her friends and family.

No. They do not mean the same thing. An absorption as you have rightly stated, indicates that the person is engrossed in something. However, this is transient and usually lasts a relatively short time (compared to an obsession) while an obsession is continuous and may be positive or negative.

For example, absorption may be used thus: John has a presentation to deliver by 8 a.m tomorrow and he is running late on his preparations. This explains his absorption over the past three hours.

Whereas, obsession may be used thus: Right from his childhood, John has had an obsession for presentations and he is very passionate about them.
