ca - the word ca; avadhāraṇe - in emphasis; ihā - here; api - the word api; samuccaye - in the sense of an aggregate; dhṛtimanta - fully saturated; hañā - becoming; bhaje - worship; pakṣi-mūrkha-caye - dull creatures like the birds, the most foolish.

“The word ‘ca’ is for emphasis, and the word ‘api’ is used to indicate an aggregate. Thus it is to be understood that even dull creatures [birds and illiterates] can also be situated in endurance and engage in Kṛṣṇa’s devotional service.
