From the entrance of Lord Danvantri Sanctum, get down through the stairs, and take left. One can find ChandraPushkarini, on the right. Proceed straight and you will find a blue colour board, which bears the direction to Ranganayaki Thayar Sanctum.
One can find Ayinthu Kuzhi (Five holes) below the board. This place is known as Ayinthu Kuzhi Moondru Vasal. Ranganayaki Thayar comes and places her fingers in these 5 holes, without bending her elbow and knee, and sees the paramapada vaasal (which is opposite to Ayindhu Kuzhi) waiting for the rival of Lord Sri Namperumal.
This place has three entrances around it, hence, it is called as Ainthu Kuzhi Moondru Vaasal.
On your left side, you can find Sri Lakshmi Narayana Perumal Sanctum. Here, Sri Mahalakshmi is seen seated on Lord Vishnu's lap.
By worshipping Lakshmi Narayana Perumal, the devotees get the complete blessings of the divine couple, as the lord bestows welfare, success, prosperity and a fulfilled life for the devotees and their families.
