CC Ādi 4.4

mūla-ślokera artha karite prakāśa
artha lāgāite āge kahiye ābhāsa

Translation: 

Just to explain the original verse, I shall first suggest its meaning.

CC Ādi 4.5

caturtha ślokera artha ei kaila sāra
prema-nāma pracārite ei avatāra

Translation: 

I have given the essential meaning of the fourth verse: this incarnation [Śrī Caitanya Mahāprabhu] descends to propagate the chanting of the holy name and spread love of God.

CC Ādi 4.6

satya ei hetu, kintu eho bahiraṅga
āra eka hetu, śuna, āche antaraṅga

Translation: 

Although this is true, this is but the external reason for the Lord’s incarnation. Please hear one other reason — the confidential reason — for the Lord’s appearance.

Purport: 

In the third chapter, fourth verse, it has been clearly said that Lord Caitanya appeared in order to distribute love of Kṛṣṇa and the chanting of His transcendental holy name, Hare Kṛṣṇa. That was the secondary purpose of Lord Caitanya’s appearance. The real reason is different, as we shall see in this chapter.
