Jinavara Visuddhidevaryavongse

Somdet Phra Maha Samana Chao Kromma Phra Jinavara Visuddhidevaryavongse (; ; 16 December 1859 – 25 August 1937), born Prince Bhujong Jombunud, was the 11th Supreme Patriarch of Thailand and a senior monk of the Dhammayuttika Nikaya. He served as Supreme Patriarch from 20 August 1921 until his death in 1937. During his lifetime, he was styled Somdet Phra Sangharaja Chao Kromma Luang Jinavara Sirivaddhana, also styled HRH Prince-Patriarch Jinavara. In July 2025, King Vajiralongkorn posthumously elevated his royal and ecclesiastical rank to the title Somdet Phra Maha Samana Chao. During his tenure, he oversaw the Dhammayuttika order, chaired Mahamakut Buddhist College, and supervised the revision and publication of the Siamrat edition of the Pāli Canon. He belonged to the Chakri dynasty through the line of King Rama III.

As a child, he studied Thai letters with his grandmother, Chao Chom Manda Samrit. After his tonsure ceremony, King Vajiravudh sent him to study at Raffles School in Singapore for about nine months. He later continued his English studies in Bangkok and studied Khmer script under Phraya Si Sunthon Wohan.

Ordination and monastic studies In 1873, at the age of 14, he was ordained as a novice at Wat Phra Si Rattana Satsadaram. His preceptor was Pavares Variyalongkorn, and Prince Arun Niphakhunakon acted as the karmavācācariya. After his ordination, he resided at Wat Ratchabophit.

He received full ordination on 29 June 1879 at Wat Phra Si Rattana Satsadaram. His preceptor was Somdet Phra Wannarat (Thap Buddhasiri), while Ariyavangsagatayana (Sa Pussadeva) of Wat Ratchapradit served as karmavācācariya. His Pali dharma name was Sirivaḍḍhana.

Ecclesiastical career Jinavara became the second abbot of Wat Ratchabophit in 1901, succeeding Prince Arun Niphakhunakon.

On 22 January 1910, he was promoted with the title Kromma Muen Chinavorn Sirivaddhana. In 1913, he was appointed deputy head of the Dhammayuttika order.

Following the death of Vajirananavarorasa on 2 August 1921, King Vajiravudh appointed Jinavara as Supreme Patriarch on 20 August 1921. He was the first Supreme Patriarch of the Rattanakosin period to receive the style Somdet Phra Sangharaja Chao.

Jinavara held the office of Supreme Patriarch during the reigns of Vajiravudh, Prajadhipok, and Ananda Mahidol. He also succeeded Vajirananavarorasa as head of the Dhammayuttika order and served as chairman of Mahamakut Buddhist College from 1921 until his death.

Scholarship and religious work

Siamrat edition of the Tipiṭaka During his tenure as Supreme Patriarch, Jinavara chaired the revision and printing of the Siamrat edition of the Tipiṭaka. King Prajadhipok ordered the project in 1925 in honour of King Vajiravudh. The revision used the 35-volume printed Tipiṭaka of 1893 as its basis and expanded the revised edition to 45 volumes.

Writings Jinavara's works included translations and textbooks such as the Abhidhānappadīpikā, a Pali–Thai dictionary, the Mahānipāta Jātaka, Nithan Ton Banyat, and Samanera-sikkha. These works were used in Pali and Buddhist studies by monks, novices, and laypeople.

The first Dhamma Studies examination was instituted on 24 August 1929. By extending organized instruction and examinations beyond monastic institutions, the system enabled laypeople, including women and young people, to study Buddhist doctrine and receive formal assessment. This broadened access to religious and moral education regardless of gender, age, or social status.

The system expanded throughout Thailand, becoming an established component of Buddhist education for students and the general public. In 2026, the Sangha Supreme Council of Thailand approved a project commemorating the forthcoming centenary of the programme. The council designated Jinavara's work as a significant development in educational expansion and lifelong learning, associating its legacy with educational access, cultural preservation, and peace.

Personal symbols

During his lifetime, Kromma Luang Jinavara Sirivaddhana used several personal emblems based on his Thai initials, ช.ส. (Jinavara Sirivaddhana). Some featured a five-tier yellow umbrella signifying his rank as Somdet Phra Sangharaja Chao. Following his death, Prince Narisara Nuvadtivongs designed a revised version of the initialed, umbrella-topped emblem for the memorial fan distributed at Jinavara's royal cremation. His royal cremation was held on 21 February 1938 at Wat Thepsirinthrawat.

Posthumous elevation On 17 July 2025, King Vajiralongkorn posthumously elevated Jinavara's royal remains in both royal and ecclesiastical rank. The proclamation elevated him from Phrachao Worawong Thoe Kromma Luang Jinavara Sirivaddhana, Somdet Phra Sangharaja Chao to Phrachao Borommawong Thoe Kromma Phra, residing at the rank of Somdet Phra Maha Samana Chao. The short form of the new title was Somdet Phra Maha Samana Chao Kromma Phra Jinavara Visuddhidevaryavongse. He built a mondop in this temple to use as a crematorium for his mother because she was a commoner so she may not allowed to be made a royal funeral. When Mom Pun, Jinavara's mother, died in 1929, King Prajadhipok, as his disciple, gave his royal patronage for her funeral as a mother of the Supreme Patriach of Siam at Wat Thepsirinthrawat, Bangkok. After that, Jinavara brought her ash to place in this mondop along with a Buddha footprint replica. When Jinavara died in 1938, the regency council of Thailand under King Ananda Mahidol renamed this temple as "Wat Jinavararam" (วัดชินวราราม) and gave a status of a royal temple (third class), becoming the first royal temple in Pathum Thani Province.
