Whether it is habitual patterns or a fixed ideology, creed, or belief system, the human mind requires a framework within which to limit its action. The disruption of that framework creates extreme discomfort for the mind, and this can be in the form of disorientation or a feeling of chaos and confusion which makes effective mental action well nigh impossible. The wisdom traditions of the world tend to recognize this when they indicate that one should not undermine a person’s belief system if one is not capable of replacing it with another. Those who have their fixed belief systems disturbed may tend towards extreme and unregulated behavior that is destructive to themselves or others, and they may feel lost and unable to function effectively. Even spiritual seekers, while they remain rooted in the mind, are more comfortable having a pattern, routine or practice laid out for them to follow. If they escape this framework without shifting the standpoint to the supramental, they frequently begin to believe that the world and its forms are simply illusory in nature. This is the nature of the mind.
The supermind, on the other hand, functions without these limitations as Sri Aurobindo intimates: “…the supermind is not bound by any representation of system, though it is perfectly able to represent and to arrange and construct in the living substance of the truth for the pragmatic purpose of the Infinite.”
“The mind assailed by the vastness and freedom of the supramental loses itself and finds no firm footing in the vastness. The supermind, on the contrary, can in its freedom construct harmonies of its thought and expression of being on the firm ground of reality while still holding its infinite liberty and rejoicing in its self of infinite vastness. All that it thinks, as all that it is and does and lives, belongs to the truth, the right, the vast, satyam, rtam, brhat.”
