They are spread in various divisions known as thanas. Dwellers of various thanas in Chittagong too have distinct differences in their languages. However, they follow the same family or kinship pattern, religious ceremonies, New Year festivals and various celebrations. According to the history of Buddhism in Bangladesh there was once a deformation of the religious system; particularly the role of priests who were not recognized by the State and had no sponsors. As there was no government supports much of their cultural ceremonies and religious festivals were incorporated with Hindu system. Outside they were like Hindus but among themselves they retained the Buddhist identity which is significant mainly by names. Priests were a set of people known as raoli purohits. The term purohit is still used by Hindus to refer to a class of their priests. Ven. Saramedha (Saramitra) who was trained according to Burmese Buddhism played an important role in early 19th century for the revival of this religion and establish in the original form. However, even today, many of their cultural aspects including the form of dresses they maintain Hindu influence. The form of Buddhism among them is according to Theravāda tradition. They believe that every Buddhist male should be ordained as a Buddhist monk at least for a weak. Otherwise, he will never be reborn as a human and hence no probability of his liberation from samsāra. In fact, when such people die their corpses are not carried by shoulders but holding the coffins above the knee level.
Most of the religious festivals among baruas are common to other Buddhist countries. New Year festival gained religious importance among them. The kathina festival (after three months of rainy season) is celebrated and regarded as a joyful event. They also developed a form of unwritten devotional songs known as kīrtan (or samkīrtan singing together) in praise of Buddha and good principles of life. In most of the Buddhist festivals kīrtans are sung either by a single person, in a group or only by two persons who debate taking two roles (popularly Siddhartha and Devadatta) and capturing a historical incident in Buddhas life. Sīvali pūja offering of a large number of food and fruit items in name of Arahanth Sīvali is one of the festivals not much popular among Sri Lankan Buddhists. Offerings in name of Ven.Upagupta who appears as a prominent figure in the Sanskrit avadāna literature and believed still living in nāgaloka is significant among the Baruas and Buddhists in Bangladesh as a whole. Ven. Sadhanananda popular as vanabhante (a still living forest monk, who meditated in deep forest for 12 years) from Chakma community is also venerated with great respects by them. There are many great Buddhist scholar monks from Barua community, who played responsible roles for the propagation of Buddhism in and outside the country. Ven. Atisha Dīpamkara srījñāna the founder of Tibetan Buddhism in 10th century B.C. is interpreted by many scholars as from Barua community. Ven. Karmayogi Kripasaran mahasthavir with many others was a close associate of Anagārika Dharmapala in reviving the Bodhgaya Buddhist Temple and Buddhism in India.
