To the question 'what do Karma and Guna exactly mean according to Gita?' a generic and philosophical meaning is proffered as the answer. According to this response, Karma is any act or deed, be it good or bad, which in turn produces good Karma or bad Karma respectively. But, irrespective of the best philosophical arguments one makes, based on one's own convenient interpretations, the subject dealt with in the Gita remains independent of those interpretations.
Yes, Gita does talk at length about good Karma, bad Karma, past Karma etc.; but it certainly does not use the term 'Karma' in a generic form throughout. This is why I said that defenders do not give a holistic picture while justifying Gita. Let us see what Gita says immediately after its declaration on the forming of the four-fold Varna system in verse 4.13:
From 4.14 onwards, Krishna goes on to explain what he means by Karma:
Chapter 4, Verse 15:
"Evam jnaatwaa kritam karma poorvair api mumukshubhih|
Kuru karmaiva tasmaat twam poorvaih poorvataram kritam||"
"Having known this, the ancient seekers after freedom also performed actions; therefore, do thou perform actions as did the ancients in days of yore."
