Atharva Veda 6.108: A prayer for wisdom

Intelligence, come first to us with store of horses and of kine!
Thou with the rays of Sūrya art our worshipful and holy one.

The first, devout Intelligence, lauded by sages, sped by prayer, Drunk by Brahmachāris, for the favour of the Gods I call.

That excellent Intelligence which Ribhus know, and Asuras, Intelligence which sages know, we cause to enter into me.

Do thou, O Agni, make me wise this day with that Intelligence.
Which the creative ishis, which the men endowed with wisdom knew.

Intelligence at eve, at morn, Intelligence at noon of day, With the Sun's beams, and by our speech we plant in us Intelligence.
