Every force that acts in the universe operates under its own principle of action. The human mind, unable to see the larger principles at work, treats forces in many cases as if they are simply random and incomprehensible. Western scientists, following up on the alchemists of the past, began to search for physical principles that operate in the world and devised laws of physics by which they can predict physical forces at work. This was followed by biochemistry and chemistry. Psychologists and sociologists began to look for principles that guide the action of individuals and groups of individuals. Nowadays, it is fairly well agreed that each force acts according to its unique principle of action.
Sri Aurobindo extends our understanding of this factor in the realm of spiritual action as well. The supreme Supramental Force, the Divine Shakti, acts under its own impulsion according to its own light as an evolutionary and transformative force. Thus, it does not act when the vessel that wants to receive it is either unready or impure, and thus, prone to misuse of the force for purposes other than what is intended by it.
“If behind your devotion and surrender you make a cover for your desires, egoistic demands and vital insistences, if you put these things in place of the true aspiration or mix them with it and try to impose them on the Divine Shakti, then it is idle to invoke the divine Grace to transform you.”
“If you open yourself on one side or in one part to the Truth and on another side are constantly opening the gates to hostile forces, it is vain to expect taht the divine Grace will abide with you. You must keep the temple clean if you wish to instal there the living Presence.”
So long as there is a consciousness of the individual ego, the effort required is to tune oneself to the action and influence of the Divine Force to the exclusion of other forces, and thereby create a field in which that force can act without impediment to transform body, life and mind.
