By these activities [as mentioned above] one is able to cut down the influence of the enemies, namely lust, anger, greed, illusion, madness and jealousy, and when thus situated, one can render service to the Lord. In this way one surely attains the platform of loving service to the Supreme Personality of Godhead.
