Periyava had asked Shri Joshi to make a Kuthu Vilakku (lamp) of gold and bring it to Him. For some reason Shri Joshi could not go to the Matam and instead sent it through another devotee Shri Ramanan.
Shri Ramanan submitted the lamp to Him when he went to have His Darshan. On seeing the lamp Periyava took it in His Hand and tells those who had assembled near Him:
“During all days of Navarathri, Ambal comes physically and sits exactly at 8 pm on the Meru in Kamakshi Amman Temple. So, take this lamp, light it and place it near the Meru! Since the Meru will be become hot due to the heat of the flame, prepare a ball of sandhanam (sandalwood paste) and place the lamp on top of it!
