Cakrapuṣkariṇī literally means ‘tank of the discus’.
Once Viṣṇu dug a pit with his cakra or discus and sat in it to perform severe penance. The whole pit was filled with his perspiration. In admiration of this penance Śiva shook his head. Due to this, his ear-ornament fell into this pit. Hence it came to be known as ‘Cakrapuṣkariṇī or ‘Maṇikarṇikā’. It is the same Maṇikarṇikā Ghāṭ of the river Gaṅgā in Vārāṇasī or Kāśī.
