43. O Almighty Ruler, we do not know the means of security for creatures beset with fear everywhere other than resorting to Thy feet, — the feet of Thee that commandest the state of heaven (Moksha); Brahma is immensely filled with fear, therefore Brahma who lives through the two halves of Parardha period is afraid of the time when Thou movest Thy brows; then it goes without saying that creatures produced by Brahma are full of fear.
