Know that enlightenment can be attained by oneself, it need not be taught in schools or created for you. Your mind is the problem, it is all a borrowed commodity subject to the whims of society. Once you grow into realization of all the society has poisoned onto you, and you are able to train your mind, you cannot miss the resulting freedom that comes. You cannot miss it. It is as if you have had a stroke and cannot move one side of your body. Then you rise into awareness and can then move the side of your body that has been paralyzed.
Personally, when I grew in awareness, I am not sure if I have achieved enlightenment, but something that I did not know stirred and started to function. You start to exist without tension and stress. Your imaginary problems disappear, negative feelings evaporate. Recall that positive energy (thoughts) and negative energy (thoughts) have the same amount of energy. They are two sides of the same coin. When anger disappears, love, light, and compassion remain. When the ugly side of your mind evaporates, it leaves behind a shining treasure.
Be relieved that your negative thoughts are just that…negative thoughts. They are imaginary and do not have their own life. They are like leeches that are counting on you to nurse them and feed them, coddle them. If you just relax and watch your anger detached, and you give it no energy and no life, the anger is totally impotent. Slowly, you will emerge out of your own thought patterns that have haunted you all your life.
