Here is the structure of Chaitanya Charitamrit(CC).
CC is divided into three parts
- Adi Leela
- Madhya Leela
- Antya Leela
Adi lila deals with Chaitanya Mahaprabhu's life before Sanyas(till the age of 24 years)
Madhya Leela mainly contains His pastimes when He went on tour of India.
The last part,Antya Lila speaks about His pastimes in Jagannath Puri.
Each of these sections have chapters and each chapter in tern has verses.
Now from your question we know that you are talking about 2.15-16 i.e. Chapter 2, verse 15-16. But which Lila? That we do not know. In any case I'l link below Prabhupada's translation of verses 2.15-16 of all three Leelas.
Adi Lila 2.15-16
[Lord Brahmā said:] “The opulences of the impersonal Brahman spread
throughout the millions and millions of universes. That Brahman is but
the bodily effulgence of Govinda.
“I worship Govinda. He is my Lord. Only by His grace am I empowered to
create the universe.”
Madhya Leela 2.15-16
Śrī Caitanya Mahāprabhu used to express His mind in this way: “Where
is the Lord of My life, who is playing His flute? What shall I do now?
Where should I go to find the son of Mahārāja Nanda?
“To whom should I speak? Who can understand My disappointment? Without
the son of Nanda Mahārāja, My heart is broken.”
Antya Leela 2.15-16
In this way Śrī Caitanya Mahāprabhu delivered the entire three worlds,
not only by His personal presence but also by empowering others. I
shall briefly describe how He empowered a living being in Bengal.
In Āmbuyā-muluka there was a person named Nakula Brahmacārī, who was a
perfectly pure devotee, greatly advanced in devotional service.
So from this we know that the source from where you read this verse is a very very bad translation to say the least. It is nowhere even little related to correct translation.
In any case you can read Chaitanya Charitamrit here.
