The notes of Murāri Gupta form the basis of the Ādi-līlā, and Svarūpa Dāmodara's diary provides the details for the Madhya- and Antya-līlās.
The first twelve chapters of the Ādi-līlā constitute the preface for the entire work. By referring to Vedic scriptural evidence, Kṛṣṇadāsa Kavirāja establishes that Caitanya Mahāprabhu is the avatāra (incarnation) of God for the Age of Kali—the current epoch, which began five thousand years ago and is characterized by materialism, hypocrisy, and dissension. The author also proves that Caitanya Mahāprabhu is identical to Lord Kṛṣṇa and explains that He descends to liberally grant the fallen souls of this degraded age pure love of God by propagating saṅkīrtana—literally, "congregational glorification of God"—especially by organizing massive public chanting of the mahā-mantra: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare.
