The most known Law is the Law of Attraction. It became practically a household name due to the success of the The Secret (2006) - both the book and the movie. Millions of people worldwide started to read and learn about the Law of Attraction.
In his great book A Happy Pocket Full of MoneyDavid Cameron share with us his views about these governing laws:
Everything in this universe runs under universal laws that never err even once. To be in the flow - to live in harmony with these laws - leads you to being all-round prosperous. Such harmony results in effortless well-being and prosperity, simply because you would be riding the currents that build and maintain all creation.
He goes on to say:
"a universal law is a bond that connects all experience so as to achieve total knowing.... and it is important to know that these laws do not punish you for breaking them; they cannot be broken. Suffering simply comes up when you try to ride against them"
