Caitanya-caritāmṛta 15.117
śuni’ harṣe kahe prabhu — “kahile niścaya yāṅhā haite kṛṣṇa-bhakti sei guru haya”
[shuni’ harshe kahe prabhu — “kahile nishchaya yaanhaa haite krishna-bhakti sei guru haya”]
Blended reading (Sanskrit + English inline)
śuni’ harṣe kahe prabhu — “kahile niścaya yāṅhā haite kṛṣṇa-bhakti sei guru haya”
Hearing Mukunda dāsa give this proper decision, Śrī Caitanya Mahāprabhu confirmed it, saying, “Yes, it is correct. One who awakens devotion to Kṛṣṇa is certainly the spiritual master.”
