When you cast magick, meditate, or focus on the energy otherwise to create an effect in your life through spiritual means.. do you ever wonder how your daily life factors in? The energy that you build to achieve a specific effect has to remain focused and balanced until it's effect has actually come to pass. Until then.. the little things can mess it up. Things most people don't think about but really need to.
Your emotions are a type of energy- and an important one. Your emotions bridge areas of your awareness from the physical to the spiritual when it comes to the energy, and if your emotions are chaotic or imbalanced, the energy around you will be as well. If you cast a spell to make yourself seem more attractive to someone and then have an emotional breakdown- well- your negative emotions will wreck havoc on the energy you tried to cast and effectively mess up what you were trying to do.
When casting a spell or focusing on the energy for any purpose it is very important that you remain in a state that will benefit that purpose until its completion. You must constantly be aware of that purpose and align yourself mentally and emotionally with it(have thoughts and emotions that are of the same energy and force as the energy you are trying to work with)- this will strengthen it. Also be very mindful of your physical actions and interactions because these will also effect the energy through your intent and feeling. Maintaining energy for a period of time in order to accomplish something can be quite delicate because of this and most people simply destroy the energy they tried to create without meaning to or knowing about it- be ever mindful and vigilant of yourself in order to find success in your workings.
