Śrī Caitanya Mahāprabhu has not written any books. He only spoke these eight verses called the Śikṣāṣṭakam. These verses are not ordinary. They are more important than the Gītā. These eight ślokas are so important. The Vedas and Upaniṣads cannot be compared to these ślokas. The Vedas have come from Matsyadeva or any other incarnation like Garbhodakṣāyī Viṣṇu. They have not come from Kṛṣṇa Himself. Kṛṣṇa spoke the Gītā to Arjuna. So, Gītā is also important. But it was Dvārkādhīśa Kṛṣṇa who spoke the Gītā. And he was sitting on the chariot of Arjuna. Through the medium of Arjuna, Dvārkādhīśa Kṛṣṇa instructed all the conditioned souls. The essence of all the Vedas and Upaniṣads are the ślokas: man-manā bhava mad-bhakto and sarva dharmān parityajya. But the essence of the Gītā and Śrīmad-Bhāgavatam are these eight ślokas spoken by Śrī Caitanya Mahāprabhu. In these ślokas, He has explained sambandha, abhidheya, and prayojana.
