aiśvarya-jñānete saba jagat miśrita
aiśvarya-śithila-preme nāhi mora prīta
Synonyms: 
aiśvarya-jñānete — with knowledge of the opulences; saba — all; jagat — the world; miśrita — mixed; aiśvarya-śithila-preme — to love enfeebled by opulence; nāhi — there is not; mora — My; prīta — attraction.
Translation: 
“Knowing My opulences, the whole world looks upon Me with awe and veneration. But devotion made feeble by such reverence does not attract Me.
Purport: 

After His appearance, Lord Kṛṣṇa thought that He had not distributed the transcendental personal dealings with His devotees in dāsya, sakhya, vātsalya and mādhurya. One may understand the science of the Supreme Personality of Godhead from the Vedic literatures and thus become a devotee of the Lord and worship Him within the regulative principles described in the scriptures, but one will not know in this way how Kṛṣṇa is served by the residents of Vrajabhūmi. One cannot understand the dealings of the Lord in Vṛndāvana simply by executing the ritualistic regulative principles mentioned in the scriptures. By following scriptural injunctions one may enhance his appreciation for the glories of the Lord, but there is no chance for one to enter into personal dealings with Him. Giving too much attention to understanding the exalted glories of the Lord reduces the chance of one’s entering into personal loving affairs with the Lord. To teach the principles of such loving dealings, the Lord decided to appear as Lord Caitanya.
