CC Madhya 4.8

tāṅra sūtre āche, teṅha nā kaila varṇana
yathā-kathañcit kari’ se līlā kathana
Word for word: 
tāṅra — his; sūtre — in the synopsis; āche — there are; teṅha — he; kaila varṇana — did not describe; yathā-kathañcit — something of them; kari’ — doing; se — these; līlā — of pastimes; kathana — narration.
Translation: 
Some of the incidents he did not describe elaborately but only summarized, and these I shall try to describe in this book.
