The hearing of Śrīmad-Bhāgavatam performed by professional men is different from the transcendental hearing of Mahārāja Parīkṣit. Mahārāja Parīkṣit was a soul realized in the Absolute Truth, Śrī Kṛṣṇa, the Personality of Godhead. The fruitive materialist is not a realized soul; he wants to derive some material benefit from his so-called hearing of Śrīmad-Bhāgavatam. Undoubtedly such an audience, hearing Śrīmad-Bhāgavatam from the professional men, can derive some material benefit as they desire, but that does not mean that such a pretense of hearing Śrīmad-Bhāgavatam for a week is as good as the hearing of Mahārāja Parīkṣit.
It is the duty of the sane to hear Śrīmad-Bhāgavatam from a self-realized soul and not be duped by professional men. One should continue such hearing till the end of one's life so that one can actually have the transcendental association of the Lord and thus be liberated simply by hearing Śrīmad-Bhāgavatam.
Mahārāja Parīkṣit had already given up all his connections with his kingdom and family, the most attractive features of materialism, but still he was conscious of his material body. He wanted to be free of such bondage also by the constant association of the Lord.
