Knowledge of self-realization, even though freed from all material affinity, does not look well if devoid of a conception of the Infallible [God] . What, then, is the use of fruitive activities, which are naturally painful from the very beginning and transient by nature, if they are not ultilized for the devotional service of the Lord?
It can only be fruitful when made subservient to the devotional service of the Lord. In the Bhagavad-gita also it is confirmed that the result of such fruitive work may be offered for the service of the Lord, otherwise it leads to material bondage. The bona fide enjoyer of the fruitive work is the Personality of Godhead, and thus when it is engaged for the sense gratification of the living beings, it becomes an acute source of trouble. SB 1.11.12
