The pure devotee is never interested in material topics. Sri Caitanya Mahaprabhu has strictly prohibited His devotees to talk about worldly matters. Gramya-varta na kahibe: [Cc. Antya 6.236] one should not indulge in talking unnecessarily about news of the material world. One should not waste time in this way. This is a very important feature in the life of a devotee. A devotee has no other ambition than to serve Krsna, the Supreme Personality of Godhead. This Krsna consciousness movement was started to engage people twenty-four hours daily in the service of the Lord and in His glorification. The students in this institution engage in the cultivation of Krsna consciousness from four in the morning to ten at night. They actually have no opportunity to waste their time unnecessarily by discussing politics, sociology and current events. These will go their own way. A devotee is concerned only with serving Krsna positively and seriously.
