Śrīla Bhakti Niketana Turyāśramī Mahārāja took shelter of the lotus feet of the Founder-Ācārya of the Śrī Caitanya Gauḍīya Maṭha, Nitya-līlā-praviṣṭa oṁ viṣṇupāda aṣṭottara-śata Śrī Śrīmad Bhakti Dayita Mādhava Gosvāmī Mahārāja at the young age of 14.
Accepting Prasanna Kumāra Giri as his father and Dīpikā Giri as his mother, he appeared in the year 1930 in Balasari (Choṭa Balasari), Goalpara district Assam. After his birth he was named Bhadreśvara Giri. His elder brother is Sameśvara Giri and his younger brother is Bhubaneśvara Giri. He was very dear to his parents and from a young age he was very inclined to writing. Later he was admitted to the local school where he started to study.
He met his spiritual master Śrīla Bhakti Dayita Mādhava Gosvāmī Mahārāja in the house of Rādhā Mohana Prabhu (a disciple of Śrīla Bhakti Siddhānta Sarasvatī Gosvāmī Prabhupāda). In 1950 he left home and by holding the hand of his beloved Gurudeva came to Sarbhog Maṭha (the first Maṭha established by Śrīla Bhakti Siddhānta Sarasvatī Gosvāmī Prabhupāda in Assam and who named it Śrī Gauḍīya Maṭha).
He started staying there and learned the rules and regulations of brahmacārī life under the guidance of Śrīla Bhakti Vijñāna Āśrama Mahārāja (a disciple of Śrīla Bhakti Siddhānta Sarasvatī Gosvāmī Prabhupāda) who was the Maṭha-in-charge of that Maṭha. In the year 1951 by the request of Śrīla Bhakti Vijñāna Āśrama Mahārāja, Śrīla Bhakti Dayita Mādhava Gosvāmī Mahārāja initiated the young boy Bhadreśvara Giri and gave him first and second initiation simultaneously and he was given the name Bhagavān dāsa Brahmacārī.
Bhagavān dāsa served there as a pūjārī for a few years and then by the request of his spiritual master he was sent to Māyāpura to serve as a pūjārī at Śrīvāsa-aṅgana and Advaita-bhavana. He was managing there as a pūjārī and cook. At that time, Parameśvarī dāsa Brahmacārī (a disciple of Śrīla Bhakti Siddhānta Sarasvatī Gosvāmī Prabhupāda) was the Maṭha-in-charge of Yogapīṭha, Śrīvāsa-aṅgana and Advaita-bhavana. While serving in Śrīvāsa Aṅgana and Advaita-bhavana for several years he was again sent to Svānanda-sukhadā-kuñja in Godrumadvīpa by Pūjyapāda Bhakti Vilāsa Tīrtha Gosvamī Mahārāja as there was a scarcity of pūjārī and cooks.
A few years later Śrīla Bhakti Dayita Mādhava Gosvamī Mahārāja founded Iśodyāna and established his own mission — Śrī Caitanya Gauḍīya Maṭha. After getting the land in Iśodyāna Māyāpura, he started a sanskrit vidyā-pīṭha. Lokanātha dāsa Brahmacārī Kāvya-vyākāraṇa-tīrtha (a disciple of Śrīla Bhakti Dayita Mādhava Gosvāmī Mahārāja) was appointed as the teacher of the school. Bhagavān dāsa Brahmacārī learned grammar and completed the Vyākāraṇa-tīrtha course at the sanskrit school. Later he gained admission in Navadvīpa Government Sanskrit College in Navadvīpa. He studied Vaiṣṇava philosophy and kāvya (Vaiṣṇava poetries) there and received his degree after which he would participate in college debate programs and would defeat the students using scriptural evidence.
Later Śrīla Bhakti Dayita Mādhava Gosvāmī Mahārāja opened another school in a rented house at 86A Rāsa-bihārī Avenue in Kolkata and named it Gauḍīya Sanskrit Mahā Vidyālaya. Bhagavān dāsa was given the responsibility of teaching Vaiṣṇava philosophy to the students. He fully engaged himself in teaching and studying Vaiṣṇava literatures and philosophy. He received the title ‘Bhakti Ketana’ (which means the flag bearer of devotion) from his spiritual master on Gaura Pūrṇimā in Māyāpura.
It was the desire of his beloved spiritual master that he should educate himself to become a renowned scholar in Sanskrit. To fulfil the desire of his spiritual master he spent days and nights in studying scriptures. Though Śrīla Bhakti Dayita Mādhava Gosvāmī Mahārāja wanted to award him with the renounced order of life (sannyāsa), due to his engagements in studying and teaching in the school he was unable the accept it. After the disappearance of his spiritual master Śrīla Bhakti Dayita Mādhava Gosvāmī Mahārāja in 1979, he was engaged in preaching activities in various parts of Bengal and throughout India with his beloved godbrother Śrīla Bhakti Vallabha Tīrtha Gosvāmī Mahārāja.
On Gaura Pūrṇimā (the 500th year birth anniversary of Caitanya Mahāprabhu) Bhagavān dāsa Brahmacārī accepted the renounced order of life (sannyāsa) from Śrīla Bhakti Vallabha Tīrtha Gosvāmī Mahārāja and thus he was given a new name Śrīla Bhakti Niketana Turyāśramī Mahārāja. He travelled to various places with Śrīla Bhakti Vallabha Tīrtha Gosvāmī Mahārāja to spread the message of Hari, Guru and Vaiṣṇava.
After Śrīla Bhakti Vallabha Tīrtha Mahārāja went to preach the message of Caitanya Mahāprabhu to the western world, he engaged Śrīla Bhakti Niketana Turyāśramī Mahārāja in writing spiritual articles for Śrī Caitanya Gauḍīya Maṭha’s monthly magazine Caitanya Vāṇī. This magazine still gets published from Śrī Caitanya  Gauḍīya Maṭha. Mahārāja started writing spiritual articles in 1996 and until now he is contributing to this magazine even at an advanced stage of life. Aside from written articles, he has published several books in Bengali like Upaniṣad-tātparya, Bhakta Bhagavāner-kathā, Veṇu-gīta, Gitār-pratipadya, Viraha Vidura, Darśana Prabhā, Bhagavat-sākṣāt-kara, Dhara Pāpe Baḍa (the sinful earth), Yuga Dharma, Vede Go-Mangso and Kaliyuger Yuga Dharma (English).
Śrīla Bhakti Niketana Turyāśramī Mahārāja is currently 91 years old and devotees from various saṅgas are coming to seek his shelter and listen to his heart touching hari-kathā. He is one of the most senior and pure devotees living on this planet. Despite his old age, he is still giving classes on Gauḍīya Vaiṣṇava philosophy.
