Question

Rabbi, hello,
On the matter of holiness, the mundane, and sanctifying matter, during my studies I came across a fascinating chapter in Leshem (Derushei Olam HaTohu, Part I, Discourse 5, section 7).
I put these ideas up as a post, and Rabbi Amir Shechter recommended that I send them to you…
“And behold, in the worlds of Beriah, Yetzirah, and Asiyah there are the holy and the mundane, the pure and the impure. And we are obligated to draw a distinction and separation between them… And it is a complete and grave prohibition to apply the term holiness to anything that the Torah did not sanctify, and all the more so to say, Heaven forbid, that there is some holiness clothed, Heaven forbid, in something that the Torah rendered impure…
And in the holy Zohar, Parashat Pekudei: ‘For all that is mundane is not on the side of holiness at all; the mundane is from the side of impurity. Therefore there is a distinction between holy and mundane, because we need to separate between holy and mundane…’
So we see the great severity of attributing or associating any holiness with anything mundane, and all the more so with anything impure, Heaven forbid.
And even if the intention is not some form of worship, Heaven forbid, but only that a person thinks in his mind and intellect that there is some holiness clothed within it—behold, this is an accessory of idolatry, may the Merciful One save us…
The mundane does have a root in holiness… but it is only a root, from which all its existence and continuance are drawn; holiness itself is not actually clothed there, but only shines upon it from above and from outside…
And thus all our words have explained all these distinctions that we are obligated to establish in our hearts, namely between pure and impure, between holy and mundane, and likewise between holy and the Holy of Holies…”
