Apologetics for every day - the question

Last week I had an encounter with someone working in an office and on her desk was a sign that read "Karma is real."I have spent quite a bit of mental energy in the last week thinking how I could have best broached the gospel with this lady.  So I think I'll toss this question to you, my reader.  Tell me. What would you have said to begin the process of evangelism in this case?

Later  I'll tell you what approach I have decided on.
