Śrī Caitanya Caritamrta · Text Ādi 4.219
কংসারিরপি সংসারবাসনাবদ্ধশৃঙ্খলাম্ ।
রাধামাধায় হৃদয়ে তত্যাজ ব্রজসুন্দরীঃ ॥ ২১৯ ॥
kaṁsārir api saṁsāra-
vāsanā-baddha-śṛṅkhalām
rādhām ādhāya hṛdaye
tatyāja vraja-sundarīḥ
“Lord Kṛṣṇa, the enemy of Kaṁsa, left aside the other gopīs during the rāsa dance and took Śrīmatī Rādhārāṇī to His heart, for She is the helper of the Lord in realizing the essence of His desires.”
