How your mind works determines how you live your life. It determines whether you are at conflict with the world, or at peace with it. It determines what and how you eat, how you react to all situations, what you believe you are capable of, and what your limitations are. It determines what you can and cannot do without, what you do and don't do, what you are attracted to, and what you are afraid of. It determines what you consider to be important and unimportant, what you do with your life, and what you think life is about. It determines whether you blame or forgive, hate or love, and it determines your level of inner happiness, joy, and completion.
How your mind works determines literally everything about your life, and the relationship you have with the rest of the world.
Absolutely everything is a perception (that can be changed), and absolutely everything stems from the mind. It's not what's going on "out there" in the external world that matters. It's what's going on "in here" in your mind and heart that matters. Everything has to do with the ingrained programming of your mind.
Most people live their lives with their mind on complete autopilot, without even realizing that they have the ability to take complete control of it. These people basically live their lives in a state of sleep, completely unaware that they can change the way their mind works.
They believe they are at the mercy of how their mind works, and that their capabilities are limited. They think "this is how I am, and I can't do anything about it", when in fact nothing could be further from the truth.
Changing the ingrained flow of energy through the brain's cellular neural pathways (thought processes) is nothing more than a choice. The more you purposefully think and perceive in more positive ways, the easier it becomes.
Start by questioning society's beliefs and practices, and especially the validity of the workings of your own mind. What we think and believe to be true, is very often far from the truth, even if that opinion is held by the masses of society. The automatic consequence of that falsehood then, or even of limited relative truths, is what creates all of our suffering, individually and collectively.
So if you're tired of suffering, no matter what the shape or form of that suffering might be, seek truth, live that truth, and be that truth.
Why? Because the truth is the answer to every problem that ever has and ever will exist.
