bāhu tuli’ — raising the arms; prabhu — Lord Śrī Caitanya Mahāprabhu; bale — speaks; bala — all of you chant; hari hari — the holy name of Lord Kṛṣṇa (Hari); hari-dhvani — the sound vibration of Hari; kare — does; loka — all people; svarga-martya — in heaven, the sky and the land; bhari’ — completely filling.
Whenever the crowds were too great, Śrī Caitanya Mahāprabhu stood up, raised His hands and chanted, “Hari! Hari!” to which all the people responded, filling both the land and sky with the vibration.
