Harivarasanam is recited before closing the
Sabrimala temple door at night. Harivarasanam song, which is sung today at Sabarimala as the Lullaby at night (Urakkupattu) was composed by Sri Kambakkudi Kulathur Srinivasa Iyer. It is said that Srinivasa Iyer used to recite the composition, after the Athazha Pooja, standing in front of Lord Ayyappa at the main temple. With the efforts of Swami Vimochanananda, it came to be accepted as the lullaby by the Thantri and Melsanti. The composition has 352 letters, 108 words in 32 lines (8 stanzas).
Though there have been many versions of this song sung by many renowned vocalists, the temple plays the rendition by Dr.KJ Yesudas. Dr. Yesudas is a staunch devotee of Lord Ayyappa though being a Christian by birth. Many devotees agree that when they hear his rendition being played at night in the shrine, they feel the presence of God
Neyyabhishekam: This significant ritual involves pouring sacred ghee brought by pilgrims in their Pallikattu (Irumudi) on the idol of Lord Ayyappa. It symbolically means the merging of Jeevatma with the Paramatma.
Aham Bhramasmi and Tattvamasi: The important message given at the temple is the ultimate knowledge that you are God, Tat Tvam Asi in Sanskrit meaning "That is you". Due to this pilgrims call each other Swami. Kantararu Maheshwararu of Tazhamon family is the Tantri (Head Priest) of Sabarimala.
Tat Tvam Asi, meaning "Thou Art That" is the message that is given out by the Lord. It means, in short, you are part of the Universal Soul (in Sanskrit "Paramatma") which is the quintessence of Advaita philosophy. It also means for reaching The Paramatma or Universal Soul, you search yourself .i.e. the Jeevatma (Life soul) present in you.
