But those who worship Me, giving up all their activities unto Me and being devoted to Me without deviation, engaged in devotional service and always meditating upon Me, having fixed their minds upon Me, O son of Pritha–for them I am the swift deliverer from the ocean of birth and death.
It is explicitly stated here that the devotees are very fortunate to be delivered very soon from material existence by the Lord. In pure devotional service one comes to the realization that God is great and that the individual soul is subordinate to Him. His duty is to render service to the Lord–and if he does not, then he will render service to maya.
As stated before, the Supreme Lord can be appreciated only by devotional service. Therefore, one should be fully devoted. One should fix his mind fully on Krishna in order to achieve Him. One should work only for Krishna. It does not matter in what kind of work one engages, but that work should be done only for Krishna. That is the standard of devotional service.
The devotee does not desire any achievement other than pleasing the Supreme Personality of Godhead. His life’s mission is to please Krishna, and he can sacrifice everything for Krishna’s satisfaction, just as Arjuna did in the Battle of Kurukshetra. The process is very simple: one can devote himself in his occupation and engage at the same time in chanting Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. Such transcendental chanting attracts the devotee to the Personality of Godhead.
