As Srila Bhaktisiddhanta Sarasvati Thakura explains, the word nirapeksa means not being affected by anything material and remaining fixed in the service of the Lord. Sri Caitanya Mahaprabhu did not very much care for the roaring tumult and cry at the house of Advaita Acarya, which He heard when starting for Jagannatha Puri. Worldly moralists may criticize Sri Caitanya Mahaprabhu for being very cruel, but the Lord did not care for such criticism. As the world teacher of this Krsna consciousness movement, He actually showed that a person seriously engaged in Krsna consciousness should not be affected by worldly affection. The best course is to engage in rendering service to the Lord and to become callous to material objectives. Externally everyone is attached to material things, but if one becomes entangled in such things, he cannot make progress in Krsna consciousness. Therefore those who are engaged in Krsna consciousness should not care for the so-called morality of the material world if that morality opposes the service of the Lord. As Lord Caitanya Mahaprabhu has personally shown, one cannot properly execute Krsna consciousness without being neutral.
