CC Madhya 2.32
tāra svāda ye nā jāne, janmiyā nā maila kene,
se rasanā bheka jihvā sama
kṛṣṇera — of Lord Kṛṣṇa; adhara-amṛta — the nectar of the lips; kṛṣṇa — of Lord Kṛṣṇa; guṇa — the qualities; carita — the activities; sudhā-sāra — of the essence of all nectar; svāda — the taste; vinindana — surpassing; tāra — of that; svāda — the taste; ye — anyone who; nā jāne — does not know; janmiyā — taking birth; nā maila — did not die; kene — why; se — that; rasanā — tongue; bheka — of the frog; jihvā — the tongue; sama — like.
“The nectar from the lips of Lord Kṛṣṇa and His transcendental qualities and characteristics surpass the taste of the essence of all nectar, and there is no fault in tasting such nectar. If one does not taste it, he should die immediately after birth, and his tongue is to be considered no better than the tongue of a frog.
