Kālidāsa
The most popular theory is that Kalidasa flourished during the reign of Chandragupta II, and therefore lived around 4th-5th century CE. Several Western scholars have supported this theory, since the days of William Jones and A. B. Keith. Many Indian scholars, such as Vasudev Vishnu Mirashi and Ram Gupta, also place Kalidasa in this period. According to this theory, his career might have extended to the reign of Kumaragupta I (r. 414 – 455 CE), and possibly, to that of Skandagupta (r. 455 – 467 CE).
Kalicharan Brahma
Kalicharan felt that the identity and unity of the people could be preserved only though a change in their Society and religion. In 1905, he came across the Sarnitya Kriya written by Mohini Mohan Chattopadhay. The book contained the teaching of Swami Sibnarayan Paramahansa. Kalicharan became convinced that the adoption of the Brahma religion would be able to guide the Bodos towards progress and development and put a stop to the religious conversions. Thus at the age of 39, he got ordained into the folds of Brahmaism by Swami Sibnarayan at his residence in Kolkata. He returned to his native village with a determination to spread the religion among the Bodos. According to Bidyasagar Narzary and Malabika Mitra's Journey Towards Enlightenment " The basic ideology of Brahmaism on which the religion was based was that there was only one God. In Brahma religion this God is worshipped in the form of fire is of primordial importance". "Fire is Brahma and Brahma gives life to the entire Earth and all its beings. Brahma is Universal, endless and all encompassing. Where there is Brahma, there can be found Satya or Truth."
