Awakening the Buddha within, p.68-70

"...there are three primary reasons for dissatisfaction and unhappiness. These three reasons are called the Three Poisons or Three Fires. These afflictive states of mind are sometimes referred to as negative or conflicting emotions, also known in Sanskrit as kleshas - unhealthy emotions."
"POISON ONE: IGNORANCE OF THE TRUTH"
"In Buddhism the concept of ignorance refers to the age-old problem of delusion and confusion. Until we reach enlightenment, we are all at lease a little bit ignorant of the truth or out of touch with reality. We don't perceive the truth of how things actually are directly, without distortion or illusion. Instead, we insist on seeing things as we would like them to be. We tell ourselves stories, and we live in our fantasies."
"POISON TWO: ATTACHMENT"
"Who or what are you most attached to? Is it a person? Is it some object? Is it an attitude or a behavior pattern? Are you attached to some repetitive or even compulsive habit or way of doing things? Are you attached to money? Are you attached to status? How about ambition? Often our attachments take over our lives. It is as if we are possessed by our possessions. We want success so much that we give up real lives; we want beautiful things so much that we only see the imperfections in what we have; we become so attached to others that we try to control or own them; we become so attached to something or somebody that we become totally dependent and forget who we are.
The Dharma also teaches us that there are two poisonous subsets of attachments: pride and jealousy. We are so 'attached' to our possessions and accomplishments that they become a source of pride. This pride causes us to define ourselves by our attachments. Who am I? 'I am the president of the company'; 'I am a Ph.D.'; 'I am the doctor's wife'; 'I am the best basketball player on the block.' Pride plays a large role in maintaining a rigid persona; it fixes us in place, entangling and entrapping us, deadening the living flow of authenticity and spirit.
Jealousy, like pride, is one of the components of a dualistic world view. 'She has something more or different than I have. I want that something.' Or, 'He is trying to take something away from me. I won't let it happen.' Hanging on to pride and jealousy are manifestations of ego clinging. Purifying oneself of pride and jealousy is essential in loosening and diminishing our ego-centered and incorrect view of reality and in bringing harmony and reconciliation into our lives."
"POISON THREE: AVERSION"
"Aversion is another word for dislike." "Most frequently we form aversions, or dislikes, in response to frustrated attachments." "We don't like it when we don't get what we want; we don't like unpleasant experiences. When dislike is reinforced, it often escalates to anger, hate, and enmity."
"The Three Poisons usually work together to create pain in this fashion: Because we are ignorant of the truth, we think we can be made happy by fulfilling our attachments to a specific person, place, thing, feeling. Inevitably we are disappointed, and then aversion, dislike, or even hatred rears its ugly head."
"I think it helps to add another ingredient, or 'poison,' to this frustrating group of kleshas: resistance to change. As every psychologist (and physicist) knows, we all have a tendency to resist change, particularly in those areas where we most need transformation. Freud was very articulate in pointing out that a resistance to changing for the better is one of the defining characteristics of neurosis. The fact is that we all tend to hang on to our negative habits and frozen behavior patterns. We keep retracing our steps; we keep walking the same circular patterns. We don't climb out of our ruts, our comfort zones, however dissatisfying they really feel."

SUMMARY OF UNHAPPINESS AND DISSATISFACTION
"POISON ONE: IGNORANCE OF THE TRUTH" originates from 'not enlightened', so we have delusion and confusion, living in our fantasies.
"POISON TWO: ATTACHMENT" could be a person, an object, an attitude, a behavior pattern, a habit, such as money, a status, ambition, perfection, success, pride, jealousy, alcohol.
"POISON THREE: AVERSION" is dislike, coming from frustrated attachments, and it causes anger, hate and enmity.
"POISON FOUR: RESISTANCE TO CHANGE" is because we tend to hang on to our habits and our comfort. We are afraid to change.

I think these concepts really help, such as attachment and aversion. So now every time when my mind bothers me, I would consider it as one of them. And it does not affect me any more.
