On the seventh night Venkateswara parades in cool weather through the temple streets of Tirumala mounted on the Chandraprabha Vahanam. For the Lord, Venkatadri Vishnu, the sun and the moon are the two eyes.
Lord Vishnu of Venkatadri, who goes in procession in the morning on Suryaprabha, goes on Chandraprabha Vahana during the night, as the moon can emit its rays only during the night. The Purushasukta explains that the moon is born from the Lord’s mind, “chandrama manasojatah”.
The moon shines with the help of the sun’s rays. Hence the Chandraprabha Vahana is taken out at night only after the Suryaprabha Vahana is taken out in the morning.
Through the Suryaprabhavahana and the Chandraprabhavahana, Lord Venkatesa shows that the Sun’s heat and the moon’s coolness are both his manifestations. The sun and the moon are the god’s eyes. The humans obtain light from the sun and mind from the moon.
