The temple is on a hill facing east with a 5 tier Rajagopuram at the entrance.  There are convenient and broad steps to reach the temple.  The Deepa Sthamba is before the Rajagopuram.  There is a shrine for Idumban the head of the Muruga force.  There is a temple for the anthill at foot hills on south east side. It is believed to be the tomb of Mayuragiri Siddha where pujas are performed on new moon days.  Devotess call this anthill (Puttru in Tamil) Subbarayar. There is a shrine for guardian deity Sukkumalayan under the Palai tree on way to Mothers Valli-Deivanai shrine.  Those seeking child boon pray here.

Those facing obstacles in wedding efforts and couples separated in life pray here.

Hills belong to Lord Muruga.  Where there is a hill, there is Muruga.  Naturally, He blesses His devotees from Oothukuli Kathithamalai hills in Erode district. This is a prayer centre where Saint Agasthya worshipped the Lord.  Presiding deity Lord Vettri Velayuthaswami graces from here without his consorts Valli and Deivanai in a standing form.

After defeating and killing Surapdhma, Lord Muruga was alone here.  Valli and Deivanai came to this hill and begged Lord Muruga to marry them.  They were the daughters of Nambirajan and Indira respectively.  As this happened before the wedding, separate shrines are allocated to them.  Lord Muruga carries with Him three powers – Valli the Itcha Shakti, Deivanai the Gnana Shakti and the Vel (Muruga’s weapon) the Kriya Shakti, representing love, knowledge and action.  These are merged in Lord Muruga.  While the first two Shaktis are by His sides, the third, the Vel is placed on His chest.  Lord Muruga is an embodiment of wisdom by Himself.

Sage Agasthya took a pilgrimage to all shrines of Lord Muruga.  He was accompanied by Maharshi Narada and the Devas.  There was no water in this place to prepare the nivedhana for the puja.  Sage Agasthya was sad.  He prayed to Lord for water.  Lord promptly appeared, punched His Vel and created a spring flowing abundant water.  Happy was the Sage.  He completed the puja and quenched his thirst too.  As the spring came from a pit, the place was named Oothukuli –Oothu means spring and pit means Kuli in Tamil.  A temple was erected here for Lord Muruga who did the wonder here.

 This is a hill temple.  Lord Muruga graces from a shrine while Valli and Deivanai blesses the devotees from a separate shrine.
