Caitanya-caritāmṛta (Madhya 7.96)
While attempting to write this book,  Kṛṣṇa , let me first offer my respectful obeisances unto my spiritual master, Om Viṣṇupāda 108 Śrī Śrīmad Bhaktisiddhānta Sarasvatī Gosvāmī Mahārāja Prabhupāda. Then let me offer my respectful obeisances to the ocean of mercy, Lord Śrī Kṛṣṇa Caitanya Mahāprabhu. He is the Supreme Personality of Godhead, Kṛṣṇa Himself, appearing in the role of a devotee just to distribute the highest principles of devotional service. Lord Caitanya began His preaching from the country known as Gauḍadeśa (West Bengal). And as I belong to the Mādhva-Gauḍīya-sampradāya, I must therefore offer my respectful obeisances to our disciplic succession. This Mādhva-Gauḍīya-sampradāya is also known as Brahma-sampradāya because the disciplic succession originally began from Brahmā. Brahmā instructed the sage Nārada, Nārada instructed Vyāsadeva, and Vyāsadeva instructed Madhva Muni or Madhvācārya. Mādhavendra Purī, the originator of Mādhva-Gauḍīya-sampradāya, belonged to the Madhvācārya disciplic succession; he had many renowned disciples both in the  sannyāsa  (renounced) and household orders of life, disciples such as Nityānanda Prabhu, Advaita Prabhu and Iśvara Purī. Iśvara Purī happened to be the spiritual master of Lord Caitanya Mahāprabhu. So let us offer our respectful obeisances to Iśvara Purī, Nityānanda Prabhu, Śrī Advaita Ācārya Prabhu, Śrīvāsa Paṇḍit
