In plain words
Caitanyopāsana: Caitanya says that without attachment to Śrī Kṛṣṇa's feet and devotion, leave aside the very word 'liberation-while-living' — even the mere purification of the intellect is impossible. It is said that, purely by the magnet-like special excellence of Śrī Hari's auspicious host of qualities, and causelessly, a rapture of devotion arises in even sages and those who delight in the Ātma, though they have no [need of] worldly scriptures. With that rapture, casting off shyness and hesitation, loudly chanting the name-glorification of Śrī Hari, with hair standing on end, with streams of tears, dancing, they experience true bliss. His sacred feet keep sanctifying this universe. In this way, what arose with attachment to the Supreme, with the chanting of His name as the principal element, is Caitanya's own worship. In the chanting of the name, dancing with rapt absorption and remaining fixed in the conviction of oneness [with Him] is the principal goal.
