Concept of Karma in Bhagwad Gita and Buddhism In Hinduism, there are many philosophies developed regarding the concept of God and afterlife, and they all give their own interpretations. Regarding the Karmic approach, the main book that gives insight about that is the Bhagwad Gita.


The main concept that arises from it is that no man can exist without doing any karma (Knowingly or Unknowingly) and hence krishna says that "any Karma without attachment is the right way to not get bounded by your karmic effects".
Whereas Buddhism says, any act of Karma whether good or bad is bound to create attachment so the best way is to not indulge in any karma altogether. 


As a man can`t live without doing karma, and this will result in karmic debt, isn't the salvation of a person (Nirvana) infeasible by this approach? Are Buddhism and Bhagwad Gita on different pages, regarding the concept of karma?
Bhagavad Gita is different to Buddhism because Bhagavad Gita teaches a person can kill in war without attachment. Buddhism does not teach this because any view that believes war is duty is attachment. 

In Buddhism, there are four types of attachment: (i) sensuality; (ii) views; (iii) precepts &amp; rituals; &amp; (iv) self-views. The view that 'war is duty' is attachment. 

In Bhagavad Gita, Arjuna had the view or idea of "my family" or "jati". 'Jati' (self-identity; social-identity; caste) is attachment in Buddhism. Buddha taught attachment (upadana) is the condition (paccaya) for becoming (bhava), which is the condition for birth (jati).

The Buddha ended 'jati' ('birth') therefore had no caste &amp; no caste duty. The Buddha renounced his warrior caste, unlike Arjuna, who did his warrior duty of war &amp; killing commanded by Krishna. 

In Buddhism, the noble eightfold path is the ending of kamma. By following the noble eightfold path, an arahant (Buddha) cannot kill a human being. 

The killing Krisha recommended &amp; Arjuna performed is a crime in Buddhism. If a Buddhist monk recommends to a person to kill another person, this monk is defeated &amp; immediately not a monk.

This is the difference between Buddhism &amp; Bhagavad Gita. In Buddhism, a Buddha/arahant cannot kill or teach another to kill. 


  Just this noble eightfold path — right view, right resolve, right
  speech, right action, right livelihood, right effort, right
  mindfulness, right concentration — is the path of practice leading to
  the cessation of kamma.
