Class Forty in Section Four of The Source

The Avodah of המאור הוא בהתגלות part 6. The external world is also G-d’s. Revealing this (G-dliness in eating drinking etc.) isn’t achieved by changing it (as we do when we do Mitzvos) but by thanking Him for it, then the “space” of the world is affected by the fact that he is fully revealed, as per המאור הוא בהתגלות. This is also the ideas of כל מעשיך לשם שמים and בכל דרכיך דעיהו as explained in ושבתי בשלום ה’תשל”ח.
