The following quotes of Sri Aurobindo are from the "Divine Plan" website (no longer online)
"Inconscient is a status and power of involved consciousness in which being is plunged into another and opposite state of non-manifestation resembling non-existence so that out of it all in the material universe may be manifested. It is a bed-rock for all resistance in the individual and the world to the victory of the Spirit and the Divine Work. Man in spite of its mental power is often impotent before the inconscient and subconscient which obscure its clarity and carry it away on the tide of instinct or impulse; inspite of its clarity it is fooled by vital and emotional suggestions into giving sanction to ignorance and error, to wrong thought and wrong action, or it is obliged to look on while the nature follows what it knows to be wrong, dangerous or evil."
God wrapped his head from sight in Matter's cowl,
His consciousness dived into inconscient depths,
All-knowledge seemed a huge dark Nescience;
Infinity wore a boundless zero's form.
His abysms of bliss became insensible deeps,
Eternity a blank spiritual Vast.
