Why try to alter your mind with the use of drugs? Because they can cause the most sublime aspects of Heaven to trickle down into the well of human experience. Drugs can scale the walls of your higher self and take you to mind states that make your everyday reality seem shallow and insignificant in comparison. Drugs can sing to your soul with a haunting euphony that is futile to resist when in earshot.
With drugs, as with all things, there are polarities involved which situate themselves upon the discretion of the user. If the proper flow is channeled you will receive ecstatic realizations, states, awareness, etc. However, if the flow is bad, the proper balance of those polarities involved becomes disoriented, amid periods of trapping blindness and destruction of the self. That nefarious demon, known to the world as "addiction", has made its way into the very core of your being, in effect transforming you into a mere shadow of your former self, an automaton if you will. Thrust into such disarray, the inner integrity of your 'soul' begins to project a flagitious, life-extinguishing perspective that is damaging to you at every level. And so wily is the nature of addiction, self-diagnosis only becomes achievable by an avid and forced introspection of any layer of the self which is suspected to be subservient to this malady's cause; this only being possible if you are at a stage so as to perceive it as a problem. Direct and unwavering application of the will must then be utilized, in every case, to break free from the binding effects of the addiction's reign.
It is important to understand that the ramification of every action that causes a willed change to occur will bring back a reciprocal effect at some level of your being (some call this "karma", I prefer "inertia").
Here is a short story (for the kids of course) of this circumstance in symbolic prose:
"Once upon a time there were three Points that formed a triangle that held up a big part of their joy in this world. All things in the world were not perfect, but the Points were able to make the best with what they had. Suddenly two of the Points were erased, leaving only a single Point behind. This one Point was unable to maintain the balance needed to hold up the joy, and so that joy fell away... This remaining Point, feeling weak in its helplessness without the other two Points, began to sink deeper and deeper into loneliness and despair.
"One day a Demon came upon the Point. As you may or may not know, some demons feed upon individuals who are lacking certain qualities or aspects in their lives. The Point was so full of loneliness and despair at this time that it was the perfect feeding ground for demons. Also, is it not strange that the Point was unafraid of demons?
"Anyway, the Demon spoke to the Point and said that it could return the joy that had toppled off of the single Point. Not only this, the Demon said that all it asked for in return was the Point's memory of the Pen that created it. The Point was quite uncertain of this though, and voiced his concern to the Demon. To this the Demon said that the Point could sample the joy and that if it was satisfactory then the Point would be given the Key to that joy.
"The Point saw no harm in the Demon's stipulation and so agreed that he should experience a sample of the Demon's joy. Right away the Point noticed that this joy was quite different from the joy he had before, but in some inexplainable way it felt superior. It was so good to have the despair go away that the Point felt compelled to make the trade with the Demon without further question.
"What a relief it was to have a seemingly endless supply of joy. But as time went on things began to change as things do. The Key to the joy started to deteriorate and now required several turns to open the door that it used to open with one turn. The Point became concerned and called to the Demon. The Point asked the Demon why its Key no longer worked as consistently as it once did. The Demon replied that he never told the Point that the Key would not wear out. The Demon said that his only duty was to continue urging the Point to use the Key. A crafty, clever demon indeed...
"The Point had found joy again; but it came with the price of having to rely upon a failing Key to remain afloat amidst a sea of loneliness and despair. That is the moral of this story."
