ca-śabda api-arthe, 'api'--avadhāraṇe
yatnāgraha vinā bhakti nā janmāya preme
ca-śabda—the word ca; api—of the word api; arthe—in the meaning; api avadhāraṇe—this api is used in sense of emphasis; yatna-āgraha vinā—without sincere endeavor; bhakti—devotional service; nā—not; janmāya—begets; preme—love of Godhead.
"The word ca may be used in place of api, which gives emphasis to something. Thus it means that without sincere endeavor in devotional service, one cannot attain love of Godhead.
