CC Madhya 17.80
- mūkaṁ karoti vācālaṁ
- paṅguṁ laṅghayate girim
- yat-kṛpā tam ahaṁ vande
mūkam—a person who cannot speak; karoti—makes; vācālam—an eloquent speaker; paṅgum—a person who cannot even walk; laṅghayate—causes to cross over; girim—the mountain; yat-kṛpā—whose mercy; tam—unto Him; aham—I; vande—offer obeisances; parama-ānanda—the transcendentally blissful; mādhavam—Supreme Personality of Godhead.
“‘The Supreme Personality of Godhead has the form of sac-cid-ānanda-vigraha (BS 5.1)—transcendental bliss, knowledge and eternity. I offer my respectful obeisances unto Him, who turns the dumb into eloquent speakers and enables the lame to cross mountains. Such is the mercy of the Lord.’”
