The commandment "Thou shalt not" is a clear instruction to avoid damaging or interfering with the order of things, the Divine holiness.
And if I adhere to this commandment, I let some of this holiness and light, even if unperceived, come upon me.
There are very many degrees of this light from the dark.
There are "candles" that splutter in blackness, and there are imperceptible rays that, even if unseen, are absorbed into the being.
They penetrate the unconscious and illumine the heart.
–Rabbi Adin Steinsaltz
From "Sanctity and Restraint," in The Candle of God by Rabbi Adin Steinsaltz
