The Ahom kings were given divine origin. According to Ahom tradition, Sukaphaa was a descendant of Khunlung, the grandson of the king of the heavens Leungdon, who had come down from the heavens and ruled Mong-Ri-Mong-Ram. During the reign of Suhungmung (1497–1539) which saw the composition of the first Assamese Buranji and increased Hindu influence, the Ahom kings were traced to the union of Indra (identified with Lengdon) and Syama (a low-caste woman), and were declared "Indravamsa kshatriyas", a lineage created exclusively for the Ahoms. Suhungmung adopted the title "Swarganarayan", and the later kings were called Swargadeo's (Lord of the heavens). It was during his reign that the Buranji titled "Sri Sri Swarganarayan Maharajor Jonmokotha" was written wherein the source and lineage of the Ahom kings was connected to the Hindu God, Indra, Lord of the Heaven.
