prabhu-pāche - behind the Lord; bule - was walking; ācārya - Advaita Ācārya; kariyā - making; huṅkāra - a loud vibration; hari-bola hari-bola - chant the holy name of Hari; bale - says; bāra bāra - again and again.

Advaita Ācārya would walk behind the Lord and loudly chant “Haribol! Haribol!” again and again.
