CC Ādi 3.10

aṣṭāviṁśa catur-yuge dvāparera śeṣe
vrajera sahite haya kṛṣṇera prakāśe

Translation: 

At the end of the Dvāpara-yuga of the twenty-eighth divya-yuga, Lord Kṛṣṇa appears on earth with the full paraphernalia of His eternal Vraja-dhāma.

Purport: 

Now is the term of Vaivasvata Manu, during which Lord Caitanya appears. First Lord Kṛṣṇa appears at the close of the Dvāpara-yuga of the twenty-eighth divya-yuga, and then Lord Caitanya appears in the Kali-yuga of the same divya-yuga. Lord Kṛṣṇa and Lord Caitanya appear once in each day of Brahmā, or once in fourteen manv-antaras,each of seventy-one divya-yugas in duration.

From the beginning of Brahmā’s day of 4,320,000,000 years, six Manus appear and disappear before Lord Kṛṣṇa appears. Thus 1,975,320,000 years of the day of Brahmā elapse before the appearance of Lord Kṛṣṇa. This is an astronomical calculation according to solar years.

CC Ādi 3.11

dāsya, sakhya, vātsalya, śṛṅgāra — cāri rasa
cāri bhāvera bhakta yata kṛṣṇa tāra vaśa

Translation: 

Servitude [dāsya], friendship [sakhya], parental affection [vātsalya] and conjugal love [śṛṅgāra] are the four transcendental mellows [rasas]. By the devotees who cherish these four mellows, Lord Kṛṣṇa is subdued.

Purport: 

Dāsya, sakhya, vātsalya and śṛṅgāra are the transcendental modes of loving service to the Lord. Śānta-rasa, or the neutral stage, is not mentioned in this verse because although in śānta-rasa one considers the Absolute Truth the sublime great, one does not go beyond that conception. Śānta-rasa is a very grand idea for materialistic philosophers, but such idealistic appreciation is only the beginning; it is the lowest among the relationships in the spiritual world. Śānta-rasa is not given much importance because as soon as there is a slight understanding between the knower and the known, active loving transcendental reciprocations and exchanges begin. Dāsya-rasais the basic relationship between Kṛṣṇa and His devotees; therefore this verse considers dāsya the first stage of transcendental devotional service.
