CC Madhya 8.37

tomāra kṛpāya tomāya karāya nindya-karma
sākṣāt īśvara tumi, ke jāne tomāra marma
Word for word: 
tomāra kṛpāya — Your mercy; tomāya — unto You; karāya — induces; nindya-karma — forbidden actions; sākṣāt īśvara — directly the Supreme Personality of Godhead; tumi — You; ke jāne — who can know; tomāra — Your; marma — purpose.
Translation: 
“You are the Supreme Personality of Godhead Himself; therefore no one can understand Your purpose. By Your mercy You are touching me, although this is not sanctioned by the Vedas.
Purport: 

A sannyāsī is strictly forbidden to see the viṣayīs, the materialistic people. But Śrī Caitanya Mahāprabhu, out of His boundless and causeless mercy, could show favor to anyone, regardless of birth and position.
