In the beginning of the Caitanya-caritāmṛta, Kṛṣṇadāsa Kavirāja Gosvāmī writes, “I offer my respects to my spiritual masters.” He uses the plural here to indicate the disciplic succession. He offers obeisances not to his spiritual master alone but to the whole paramparā, the chain of disciplic succession beginning with Lord Kṛṣṇa Himself. Thus the author addresses the guru in the plural to show the highest respect for all his predecessor spiritual masters. After offering obeisances to the disciplic succession, the author pays obeisances to all other devotees, to the Lord Himself, to His incarnations, to the expansions of Godhead and to the manifestation of Kṛṣṇa’s internal energy. Lord Caitanya Mahāprabhu (sometimes called Kṛṣṇa Caitanya) is the embodiment of all of these: He is God, guru, devotee, incarnation, internal energy and expansion of God. As His associate Nityānanda, He is the first expansion of God; as Advaita, He is an incarnation; as Gadādhara, He is the internal potency; and as Śrīvāsa, He is the marginal living entity in the role of a devotee. Thus Kṛṣṇa should not be thought of as being alone but should be considered as eternally existing with all His manifestations, as described by Rāmānujācārya. In the Viśiṣṭādvaita philosophy, God’s energies, expansions and incarnations are considered to be oneness in diversity. In other words, God is not separate from all of these: everything together is God.
Actually, the Caitanya-caritāmṛta is not intended for the novice, for it is the postgraduate study of spiritual knowledge. Ideally, one begins with the Bhagavad-gītā and advances through Śrīmad-Bhāgavatam to the Caitanya-caritāmṛta. Although all these great scriptures are on the same absolute level, for the sake of comparative study the Caitanya-caritāmṛta is considered to be on the highest platform. Every verse in it is perfectly composed.
In the second verse of the Caitanya-caritāmṛta, the author offers his obeisances to Lord Caitanya and Lord Nityānanda. He compares Them to the sun and the moon because They dissipate the darkness of the material world. In this instance the sun and the moon have risen together.
