Caitanya-caritāmṛta 6.88
bhakta-abhimāna mūla śrī-balarāme sei bhāve anugata tāṅra aṁśa-gaṇe
[bhakta-abhimaana moola shree-balaraame sei bhaave anugata taanra amsha-gane]
Blended reading (Sanskrit + English inline)
bhakta-abhimāna mūla śrī-balarāme sei bhāve anugata tāṅra aṁśa-gaṇe
The source of the sentiment of servitude is indeed Lord Balarāma. The plenary expansions who follow Him are all influenced by that ecstasy.
