Bhagavad Gita - Verse by Verse - Verses 3.5 to 3.10 - Session 13

Lord Krishna is impressing upon Arjuna and all of us that by merely dropping karma one will not get Moksha, more over everyone is helplessly made to do actions by their innate gunas. Therefore, Krishna says, convert karma to karma yoga through mind & sense control and by dropping any attachments towards karma. This action done as Yajna(offering) is superior to inaction.
