“The Law of Cause and Effect is uninfringeable and no one escapes from it. This law operates in every situation, in every place, at any time within the created Universe, at every level of creation.”

With karma, desire is taken into consideration for the Law of Cause and Effect. So are emotions such as anger, hatred, envy, egoism, jealousy. These can lead to negative reactions in your life. So keep in mind that physical, emotional, verbal, and mental actions (and thoughts) have repercussions.

To take this one step further to understand karma, certain students of the Law of Cause and Effect would clarify that it is also our omissions that become part of our destiny. The things we “should have done” but did not do may trigger reactions that we could consider negative.

To put the Law of Cause and Effect together with the Law of Attraction, it would then be best to keep all thoughts and actions as positive and giving as possible to attract the same into your life. And to counter the negativity of omissions, live your life to the fullest by taking the chance on things your heart calls out for you to do — live your passions and good things will happen.
