Caitanya Upanisad

Vedānta-vedyam purusam purānam caitanyātmānam viśva-yonim mahāntam tam eva viditva'ti-mrtyum eti nānyah panthā vidyate 'yanāya Knowing Caitanya, the primeval person, the source of the universe, the greatest, a person surpasses death. There is no other path for delivering the jīvas.

- Caitanya Upanișad (Verse 8)

Ya enam rasayati bhajati dhyāyati sa pāpmānāṁ tarati sa pūto bhavati, sa tattvam jānāti, sa tarati śokam / gatis tasyāste nānyasyeti |

The person who has affection for Caitanya, who worships him and meditates upon him becomes free of all sins. He becomes purified. He knows the truth. He becomes free of lamentation. He attains the goal whereas others do not.

- Caitanya Upanisad (Verse 19)

Śrila Bhaktivinoda Thākura (1838-1914) is a prominent ācārya in Gaudīya-vaisnava sampradāya. He was a pioneering spiritual leader, a householder, a magistrate working in colonial India under the British rule, a prolific preacher, writer, and poet. He wrote volumes of books reintroducing the pure teachings of Lord Caitanya at a time when those teachings had practically become lost. He composed hundreds of devotional songs glorifying Krsna to uplift the consciousness of the suffering people of this world. He corresponded with philosophers, theologians, leaders, scholars, and professors of his time and sent books, including The Life and Precepts of Lord Chaitanya, to university libraries in foreign countries, planting the seeds for a worldwide movement of Krishna consciousness. Bhaktivinoda Thākura discovered and excavated the birthplace of Lord Caitanya. Along with his devoted wise, Bhagavati Devī, he raised ten children, including the illustrious Bhaktisiddhānta Sarasvati Thākura, who would become a great spiritual leader in his own time and the spiritual master of ISKCON's founder-ācārya, His Divine Grace A.C. Bhaktivedanta Swami Prabhupāda.
