A person who is actually a devotee of Krsna does not care about so-called public opinion and Vedic or philosophical literatures. Prahlada Maharaja, who is such a devotee, always defied the false instructions of his father and the so-called teachers who were appointed to teach him. Instead, he simply followed the instructions of Narada Muni, his guru, and thus he always remained a stalwart devotee. This is the nature of an intelligent devotee. The Srimad-Bhagavatam instructs, yajnaih sankirtana-prayair yajanti hi sumedhasah [SB 11.5.32]. One who is actually very intelligent must join the Krsna consciousness movement, realizing his own self as an eternal servant of Krsna, and thus practice constant chanting of the holy name of the LordHare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare.
