What could thought possibly have to do with cause and effect? Since thought has no apparent measurable physical structure, it is considered to be spiritual. You can't see it, smell it, touch it, taste it, or even feel it, but we know it exists. It exists only as a vibration.
Remembering what we have learned from the the Law Of Attraction we know that vibrations that are of a particular frequency and intensity, attract to themselves alike vibrations, to bring into the physical world the result of the initial seed that was planted - in this case, thought. Just as the sunflower seed required nurturing (sun and water) your thought seed will grow according to whatever you feed to it or nurture it with. The thought, just like the sunflower seed, can only produce an outcome that is in relation to, and correlates with the seed that is planted. If your thought seed consists of fear, anxiety and doubt, we now know that through the predictable and unwavering Law of Attraction, those thoughts can only grow into and produce that which is in relation to the seed planted, and you will receive fearful, anxious, and doubtful results.
But here is the incredible news! By nurturing the original thought seed with healthy, concise, focused, and positive elements, it must produce results in relation to the seed planted! Plant the seeds of abundance and happiness and nurture them, then abundance and happiness must sprout and grow from them. Plant the seed of healthy, positive and fulfilling relationships, and healthy, positive and fulfilling relationships must grow. Plant the seeds of incredible health and vitality and incredible health and vitality must grow from them. The only thing that you have to do is nurture those seeds with correct thought and allow the incredible and unwavering power of the Law of Attraction to attract to you, the exact results that you desire! That is how the Law of Cause and Effect operates.
Now that you have a clear understanding that whatever acts you perform are subject to a precise reaction or process (Cause and Effect), you can then make a conscious choice as to what thoughts you think and which actions you take (or not take), and limit them to only those which will produce what you want into your life. So how do you know which actions to choose? Quite simply, by only choosing those things (thoughts, words and actions) that are in alignment with whatever it is that you are trying to attract.
The only possible thing that can stand in the way of you receiving your desires is you. It is up to you to make the conscious choice to change your thoughts, words, and actions which, with repetition, establishes the belief in your subconscious mind. The subconscious mind (including your spiritual consciousness) then releases into the atmosphere and emanates those vibrations of the thing desired which attracts to it, the events, people, circumstances, and situations that allow it to manifest or occur. You only have to be receptive to them. It is important to expect them and look for them as they occur. Believe me, if you will follow this process, they will come!
