Why should your occupation or duties in life interfere with your spiritual effort? For instance, there is a difference between your activities at home and in the office. In your office activities you are detached and so long as you do your duty you do not care what happens or whether it results in gain or loss to the employer. But your duties at home are performed with attachment and you are all the time anxious as to whether they will bring advantage or disadvantage to you and your family. But it is possible to perform all the activities of life with detachment and regard only the Self as real. It is wrong to suppose that if one is fixed in the Self one’s duties in life will not be properly performed. It is like an actor. He dresses and acts and even feels the part he is playing, but he knows really that he is not that character but someone else in real life. In the same way, why should the body-consciousness or the feeling ‘I-am-the-body’ disturb you, once you know for certain that you are not the body but the Self? Nothing that the body does should shake you from abidance in the Self. Such abidance will never interfere with the proper and effective discharge of whatever duties the body has, any more than the actor’s being aware of his real status in life interferes with his acting a part on the stage.
You ask whether you can tell yourself: “I am not the body but the Self”. Of course, whenever you feel tempted to identify yourself with the body (as you may often have to, owing to old vasanas) it may be a help to remind yourself that you are not the body but the Self. But you should not make such repetition a mantram, constantly saying: “I am not the body but the Self”. By proper enquiry into the Self, the notion ‘I am this body’ will gradually vanish and in time the faith that you are the Self will become unshakeable.
Renunciation is always in the mind, not in going to forests or solitary places or giving up one’s duties. The main thing is to see that the mind does not turn outward but inward. It does not really rest with a man whether he goes to this place or that or whether he gives up his duties or not. All that happens according to destiny. All the activities that the body is to go through are determined when it first comes into existence. It does not rest with you to accept or reject them. The only freedom you have is to turn your mind inward and renounce activities there.
