Philosophy does not teach people to make their minds a blank, does not say empty out all thoughts, be inert and passive. It teaches the reduction of all thinking activity to a single seed-thought, and that one is to be either interrogative like "What Am I?" or affirmative like "The godlike is with me." It is true that the opening-up of Overself-consciousness will, in the first delicate experience, mean the closing-down of the last thoughts, the uttermost stillness of mind. But that stage will pass. It will repeat itself again whenever one plunges into the deepest trance, the raptest meditative absorption. And it must then come of itself, induced by the higher self's grace, not by the lower self's force. Otherwise, mere mental blankness is a risky condition to be avoided by prudent seekers. It involves the risk of mediumship and of being possessed.
