upadeśa lañā - getting instructions from Śrī Caitanya Mahāprabhu; kare - join; kṛṣṇa-saṅkīrtana - the saṅkīrtana movement; sarva-loka hāse - everyone began to laugh in pleasure; gāya - chant; karaye nartana - and dance.

As soon as people received instructions from Śrī Caitanya Mahāprabhu, they began to chant the Hare Kṛṣṇa mahā-mantra. Thus everyone laughed, chanted and danced with the Lord.
