Loving qualities
Srimad-Bhagavatam
SB Canto 10.1 to 10.13
The history of Kṛṣṇa the person has been openly seen by everyone, yet only those who are in love with the Supreme Personality of Godhead can appreciate this history, whereas nondevotees, who have not developed their loving qualities, think that the activities, form and attributes of the Supreme Personality of Godhead are fictitious. Therefore this verse explains, na nāma-rūpe guṇa janma-karmabhir nirūpitavye tava tasya sākṣiṇaḥ. In this connection, Śrīla Viśvanātha Cakravartī Ṭhākura has given the example that persons suffering from jaundice cannot taste the sweetness of sugar candy, although everyone knows that sugar candy is sweet.

CC Madhya-lila
"Your loving qualities always attract Me to Vṛndāvana. Indeed, they will bring Me back within ten or twenty days, and when I return I shall enjoy both day and night with You and all the damsels of Vrajabhūmi."
