nanv addhā mayi kurvanti
 kuśalāḥ svārtha-darśinaḥ
ahaituky avyavahitāṁ
 bhaktim ātma-priye yathā
Word for word: 
nanu — certainly; addhā — directly; mayi — unto Me; kurvanti — they perform; kuśalāḥ — those who are expert; sva-artha — their own true benefit; darśinaḥ — who perceive; ahaitukī — unmotivated; avyavahitām — uninterrupted; bhaktim — devotional service; ātma — to the soul; priye — who am most dear; yathā — properly.
Translation: 
Certainly expert personalities, who can see their own true interest, render unmotivated and uninterrupted devotional service directly unto Me, for I am most dear to the soul.
Purport: 

The Supreme Lord informed the brāhmaṇas’ wives that not only they but all people who recognize their true self-interest take to the spiritual process of loving service to the Lord. Lord Kṛṣṇa is ātma-priya, the real object of love for everyone. Although each individual has his own taste and freedom, ultimately every living being is a spiritual spark of the Supreme Personality of Godhead; thus everyone’s primary loving attraction is constitutionally meant for Lord Śrī Kṛṣṇa. Loving service to the Lord should be ahaitukī, without personal motive, and avyavahitā, unobstructed by mental speculation, selfish desire or any quirk of time and circumstance.
