The Sixth Principle Of Natural Law

The 6th principle of Natural Law is the principle of Cause and Effect.

The book "The Kybalian", by Three Initiates, was originally published in 1912. I recommend you get a copy of the original book, without commentary, and read it first.

Next, in my opinion, the best seminar and commentary on these principles is given by Mark Passio. You can watch his seminars on YouTube.

Study the principles, learn how they all work together, and put it into practice to completely rearrange your life. Yes, it takes effort.

This vital information has been kept from humanity and definitely kept out of religious teachings...the very principles of creation Itself.
