Yes, the practice of a non-Catholic religion and/or “philosophy” is against Catholic teaching.
It doesn’t matter what “Kabbalah” says about itself in this regard. It is a Jewish mysticism and it is NOT Christian. It is NOT Catholic.
Catholicism is not a religion that teaches indifferentism-- that you can find many paths and they are all equal. The Church teaches that Christ is the Way and the Church is the ONE Church founded by Christ.
