Exactly at six o'clock in the evening, as the sun sets and as the full moon rises, the lights are lit simultaneously on the top of the hill, on the top of the metal lamp in the temple and at Sri Ramanasramam with chants and shouts of Arunachala Siva by the vast multitude of people who gather in this pilgrim city for Deepa Darshana, for having a view of the hill on this day which is considered to be extremely sacred. In Sri Ramanasramam the devotees gather in front of the lamp which is lit there as soon as the light on the top of the hill is sighted. Then they start chanting Ramana's composition 'Five Hymns to Arunachala'.
