Fair enough. The material is naturally seculure, but by reading the authors comments when mailed and watching it several times, I would not call this the work of the devil. I believe Jesus is the Universe and He founded the “Law of Attraction”.
I think the main thing is though that it is contrary to Catholic teaching. So whether or not you want to say it’s the work of the devil isn’t really the point. It is against what our Church says and therefore we should all think long and hard about it:

2117 All practices of magic or sorcery, by which one attempts to tame occult powers, so as to place them at one’s service and have a supernatural power over others - even if this were for the sake of restoring their health - are gravely contrary to the virtue of religion. These practices are even more to be condemned when accompanied by the intention of harming someone, or when they have recourse to the intervention of demons. Wearing charms is also reprehensible. Spiritism often implies divination or magical practices; the Church for her part warns the faithful against it. Recourse to so-called traditional cures does not justify either the invocation of evil powers or the exploitation of another’s credulity.

2123 "Many . . . of our contemporaries either do not at all perceive, or explicitly reject, this intimate and vital bond of man to God. Atheism must therefore be regarded as one of the most serious problems of our time."58
2124 The name “atheism” covers many very different phenomena. One common form is the practical materialism which restricts its needs and aspirations to space and time. Atheistic humanism falsely considers man to be "an end to himself, and the sole maker, with supreme control, of his own history."59 Another form of contemporary atheism looks for the liberation of man through economic and social liberation. "It holds that religion, of its very nature, thwarts such emancipation by raising man’s hopes in a future life, thus both deceiving him and discouraging him from working for a better form of life on earth."60
2125 Since it rejects or denies the existence of God, atheism is a sin against the virtue of religion.61 The imputability of this offense can be significantly diminished in virtue of the intentions and the circumstances. "Believers can have more than a little to do with the rise of atheism. To the extent that they are careless about their instruction in the faith, or present its teaching falsely, or even fail in their religious, moral, or social life, they must be said to conceal rather than to reveal the true nature of God and of religion."62
2126 Atheism is often based on a false conception of human autonomy, exaggerated to the point of refusing any dependence on God.63 Yet, "to acknowledge God is in no way to oppose the dignity of man, since such dignity is grounded and brought to perfection in God. . . . "64 “For the Church knows full well that her message is in harmony with the most secret desires of the human heart.”
