CC Madhya 3.119

premera utkaṇṭhā, — prabhura nāhi kṛṣṇa-saṅga
virahe bāḍila prema-jvālāra taraṅga
Word for word: 
premera utkaṇṭhā — the ecstasy of the love; prabhura — of the Lord; nāhi — there is not; kṛṣṇa-saṅga — meeting with Lord Kṛṣṇa; virahe — in separation; bāḍila — increased; prema-jvālāra — of flames of love; taraṅga — waves.
Translation: 
When Advaita Ācārya danced in that way, Lord Caitanya felt ecstatic love for Kṛṣṇa, and because of His separation, the waves and flames of love increased.
