And of the light and candle, which shine [Var. that have darkened] in them, it is stated of them: (Ecc. 12:3)... and those who look through the windows have darkened... As Qohelet said: (Ecc. 12:2) While the sun and the light shall not yet darken... etc.

And of ‘light and candle’ it is stated: (Prov. 6:23) For a candle is precept, and the Torah is light... And why do they become darkened in them? It is because they have not been striving in Torah and precept, in love and fear, which are the letters of the Name Y-Q.
