Arjuna
Krishna called upon Arjuna to stand up and face the battle, reminding him of what was in store for the evil-minded Kauravas. He adjured Arjuna to have full faith in Him and do his duty. Then Arjuna declared: "I shall do as you bid me." (Karishyevachanam thava)
Then Krishna declared, "You have now become My true devotee." And He exhorted Arjuna to rise and fight the battle which would end in the complete destruction of the Kauravas and the wicked quartet, Duryodhana, Dussaasana, Karna and Sakuni.
Arjuna was troubled in mind over the state of things around him and asked Krishna why this should happen to him when he had such faith in Krishna. Krishna then explained to him that it was not enough to remember God occasionally (when one felt the need to remember him). This kind of remembrance is a matter of convenience and expediency. What is required is ‘Anusmarana’, constant remembrance. Only that will relieve the devotee of his troubles and worries. ‘Anusmarana’ calls for remembrance at all times, in all situations. Krishna told Arjuna that he is thinking of God only on some occasions and for some specific purposes. This is not the proper way. "If you remember Me at all times, I am always with you", said Krishna. Krishna’s injuction to Arjuna was: "Remember Me at all times and carry on the fight. That alone will help you. It will confer success on you."
