"The creation is many, it is one, and it is Him."
Sounds like avoda zara. You are stating that HaShem is the creation. How could HaShem be the creation if He created the creation? Additionally if HaShem is the creation, and HaShem is eternal than that means the 'creation' eternally existed (Bereishis explictly states otherwise). Additionally consistent with your logic, we should chas v'shalom be worshipping the creation... sounds more like Hinduism or something like that, than Judaism.
You ask questions that have been answered many times. Please take the time to read the previous postings regarding this subject, especially the ones entitled "Idolatry" and "There Is Only One Infinite."
Most briefly stated, "All of existence is Hashem Blessed Be He." This is a well known statement often stated by the teachers of the mystical aspects of Torah. On his first page Reb Levi Yitzchak of Berditchev, zt"l (the Kedushas Levi) wrote, "The most important thing to remember is that G-d created all and that He is all."
The particular piece you are questioning can be seen discussed by the Lubvitcher Rebbe in a maamar from the year mem daled on the parsha Haazinu. You will see there almost the exact explanation that is found in the posting that you question.
If after reading these postings and other sources you still have any questions, feel free to write. By the way, this has been an ongoing argument between the Chassidic teachings of the Baal Shem Tov and his opponents.
Be well and Shavua Tov,
