Changes

Surrender does not ensure a smooth and unruffled and continuous progression. The reason is that your being is not yet one, nor your surrender absolute and complete. Only a part of you surrenders; and today it is one part and the next day it is another. The whole purpose of the Yoga is to gather all the divergent parts together and forge them into an undivided unity. Till then you cannot hope to be without difficulties—difficulties, for example, like doubt or depression or hesitation. The whole world is full of the poison. You take it in with every breath. If you exchange a few words with an undesirable man or even if such a man merely passes by you, you may catch the contagion from him. It is sufficient for you to come near a place where there is plague in order to be infected with its poison; you need not know at all that it is there. You can lose in a few minutes what it has taken you months to gain. So long as you belong to humanity and so long as you lead the ordinary life, it does not matter much if you mix with the people of the world; but if you want the divine life, you will have to be exceedingly careful about your company and your environment.

The supramental creation, since it is to be a creation upon earth, must be not only an inner change but a physical and external manifestation also. And it is precisely for this part of the work, the most difficult of all, that surrender is most needful; for this reason, that it is the actual descent of the supramental Divine into Matter and the working of the Divine Presence and Power there that can alone make the physical and external change possible. Even the most powerful self-assertion of human will and endeavour is impotent to bring it about; as for egoistic insistence and vital revolt, they are, so long as they last, insuperable obstacles to the descent. Only a calm, pure and surrendered physical consciousness, full of the psychic aspiration, can be its field; this alone can make an effective opening of the material being to the Light and Power and the supramental change a thing actual and practicable. <ref>http://incarnateword.in/cwsa/32/the-reason-for-their-embodiment#p1</ref>
