Śrī Caitanya Caritamrta · Text Madhya 19.161
প্রথমেই উপশাখার করয়ে ছেদন ।
তবে মূলশাখা বাড়ি’ যায় বৃন্দাবন ॥ ১৬১ ॥
prathamei upaśākhāra karaye chedana
tabe mūla-śākhā bāḍi’ yāya vṛndāvana
“As soon as an intelligent devotee sees an unwanted creeper growing beside the original creeper, he must cut it down instantly. Then the real creeper, the bhakti-latā, grows nicely, returns home, back to Godhead, and seeks shelter under the lotus feet of Kṛṣṇa.
