Patanjali offers 196 yoga sutras to increase your clarity and deepen you practice. Thought patterns are gradually mastered through learning non-attachment. Consider these five steps to begin to master your thoughts;
1) Notice whether your thoughts are colored with aversion or attraction. Do not judge. Learn to be an astute observer.
2) Nurture the lifestyle, actions, speech, and thoughts, and spiritual practices that lead in the positive direction. (rather than going in the opposite direction, away from the positive, and towards the negative).
3) Let go of the mental coloring of your thoughts that lead away from the spiritual (rather than going in the opposite direction, giving in to the attachments and aversions).
4) Raise conscious awareness to become more discerning of how you think and feel and the implications.
5) Practice consistency. Learn to choose the wiser courses of action with deliberate intention.
