Śrī Caitanya Caritamrta · Text Madhya 24.171
চ-শব্দ অপি-অর্থে, ‘অপি’ — অবধারণে ।
যত্নাগ্রহ বিনা ভক্তি না জন্মায় প্রেমে ॥ ১৭১ ॥
ca-śabda api-arthe, ‘api’ — avadhāraṇe
yatnāgraha vinā bhakti nā janmāya preme
“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.
