Firm faith and confidence are called sraddha. When one engages in the Lord's devotional service, he is to be understood to have performed all his responsibilities in the material world. He has satisfied his forefathers, ordinary living entities, and demigods and is free from all responsibility. Such a person does not need to meet his responsibilities separately. It is automatically done. Fruitive activity (karma) is meant to satisfy the senses of the conditioned soul. However, when one awakens to Krsna consciousness, he does not have to work separately for pious activity. The best achievement of all fruitive activity is detachment from material life, and this detachment is spontaneously enjoyed by the devotee firmly engaged in the Lord's service.
