Foolish persons or neophytes in Krsna consciousness often want to retire from activities without having knowledge of Krsna consciousness. Arjuna's desire to retire from activities on the battlefield was not approved by the Lord. One need only know how to act. To retire from the activities of Krsna consciousness and to sit aloof making a show of Krsna consciousness is less important than actually engaging in the field of activities for the sake of Krsna.
