CC Madhya 22.37

anya-kāmī yadi kare kṛṣṇera bhajana
nā māgiteha kṛṣṇa tāre dena sva-caraṇa
Word for word: 
anya-kāmī — one who desires many other things; yadi — if; kare — he performs; kṛṣṇera bhajana — devotional service to Lord Kṛṣṇa; māgiteha — although not asking; kṛṣṇa — Lord Kṛṣṇa; tāre — to him; dena — gives; sva-caraṇa — the shelter of His lotus feet.
Translation: 
“If those who desire material enjoyment or merging into the existence of the Absolute Truth engage in the Lord’s transcendental loving service, they will immediately attain shelter at Kṛṣṇa’s lotus feet, although they did not ask for it. Kṛṣṇa is therefore very merciful.
