Tirumandiram - 52

What for the Vedas?

Vedam Uraithaalum Vediyan Aagilan
Vedam Uraithaanum Veda Vilangida
Vedam Uraithaanum Vediyar Velvikkai
Vedam Uraithanum Meipporul Kattave

The books of knowledge called the Vedas were given to the world by Brahma himself. He however is not the author of the Vedas. He gave it so that we may know our creator. He gave the Vedas so that we might do the required Yagnas and Yagas to get what we want in this world and in the other planes of existence. He spelt out the Vedas not just that we may prosper, but to reveal the truth and the supreme reality. - SS

Tirumandiram - 51

The way home

Vedathai Vitta Aramillai; Vedathin
Odhath Thagum Aram Ellam Uladharka
Vadhathai Vittu Mathignar Valamuttra
Vedathai Odhiye Vidu Pettravar.

We are lost in a forest and it is becoming dark. We need to find out our way back home fast. Someone comes around with a torch and we follow the path shown by him and reach fast. 
The Vedas or books of knowledge which are nothing but the breath of the Lord, is the ultimate guide in showing our way home. The Vedas contain the essence of all things that we need to necessarily do. The wise ones do not debate on this. Instead, they chant the Vedas and follow its path and reach their original home, the pure and unsullied self. - SS.
