Srila Bhaktisiddhanta Sarasvati Thakura comments that one should remember that he is eternally a servant of Krsna. Whether one is engaged in material activity involving pounds, shillings and pence or is in the renounced order, he should always think that he is an eternal servant of God, for that is the real position of the living being. Taking sannyasa and dealing in pounds, shillings and pence are both external affairs. One should always consider how to please and satisfy Krsna. Thus even if one is involved in great material affairs, he will not become attached. As soon as one forgets that he is an eternal servant of Krsna, he becomes involved in material attachments. However, if one is always conscious that Krsna is always the supreme master and that he is an eternal servant of Krsna, he is a liberated person in any condition. Entangling material activities will not affect him.
