These type of thoughts gain a hold of us the more we judge and measure them. i.e I’m a bad person for having these thoughts. It is the labels and judgement that give the thoughts their power (and vibration)

Have you tried the practice of mindful awareness?
In this practice you don’t pretend that you don’t have them nor do you set yourself up for battle when you have them. Instead you allow yourself to notice the thoughts without judgment or measurement. Hello again thoughts… I’m going to move on now

There may be a time where you might spend time to reflect on why such thoughts arise but if you do again try not to judge or label yourself for having them.

The law of attraction is actually an attribute of the principle of vibration.
To over simplify: Our thoughts affect our vibration and it is vibration that creates our reality.

Personal Development of The Art of Vibration:
Mental transmutation (change) is an actual application of the principle of vibration. Perhaps you begin a heart centered way of living in your world. To change your mental state is to change your vibration. By changing your own vibration you will bend and shape your reality. (attract what you want) You may do this by an effort of action and will, by means of deliberately engaging in something that brings you joy and therefore raises your frequency. Essential oils, yoga, mantras, chanting, toning, art, reading books – any of these allows you to begin cultivating and actually shifting your thoughts, your vibration and therefore your entire life into a more enjoyable state.
