Sri Aurobindo has given up his body in an act of supreme unselfishness, renouncing the realisation in his body to hasten the hour of the collective realisation. Surely if the earth were more responsive, this would not have been necessary.
When I asked him to resuscitate he clearly answered:
“I have left this body purposely. I will not take it back. I shall manifest again in the first supramental body built in the supramental way.”
As soon as Sri Aurobindo withdrew from his body, what he had called the Mind of Light got realised in me.
The Supermind had descended long ago – very long ago – in the mind and even in the vital: it was working in the physical also but indirectly through these intermediaries. The question now was about the direct action of the Supermind in the physical. Sri Aurobindo said it could be possible only if the physical mind received the supramental light: the physical mind was the instrument for direct action upon the most material. This physical mind receiving the supramental light Sri Aurobindo called the Mind of Light.
