This is the श्री अर्विन्दाष्टोत्तर शतनामावलि or the 108 names of Sri Aurobindo that spontaneously came to a sadhak of the Ashram by name Gangadhar. He was a simple fisherman boy who didn't have any knowledge of sanskrit and this came to him. Equally it has been sung by Chinmayee Maheshwari who did not know which tune to sing it in since it did not have a particular छन्द (metre) but when she started singing the whole thing was recorded at the first attempt. The tune came.
