ālakṣya bhītas tvarito
rājña āvedayad yathā
The words buddhim ekānta-saṁsthitām indicate that as an effect of Prahlāda Mahārāja’s preaching, the students who listened to him became fixed in the conclusion that Kṛṣṇa consciousness is the only object of human life. The fact is that anyone who associates with a pure devotee and follows his instructions becomes fixed in Kṛṣṇa consciousness and is not disturbed by materialistic consciousness. The teachers particularly observed this in their students, and therefore they were afraid because the whole community of students was gradually becoming Kṛṣṇa conscious.
