Sri Aurobindo describes the experience of consciousness that occurs with the link to the overmental levels of consciousness. “We are aware of a sealike downpour of masses of a spontaneous knowledge which assumes the nature of Thought but has a different character from the process of thought to which we are accustomed; for there is nothing here of seeking, no trace of mental construction, no labour of speculation or difficult discovery; it is an automatic and spontaneous knowledge from a Higher Mind that seems to be in possession of Truth and not in search of hidden and withheld realities. One observes that this Thought is much more capable than the mind of including at once a mass of knowledge in a single view; it has a cosmic character, not the stamp of an individual thinking.”
If we reflect for a moment on the process of thought as we are used to it, we can see that there is something totally different and more powerful in terms of a thought-process taking place here, and Sri Aurobindo describes this as the stamp of the influx of the overmental gradations of consciousness, which are founded and based in the cosmic and universal Truth, even while they recognize and work out the issues related to the individual process. There are of course other manifestations of the influx of the overmental levels of consciousness which we shall explore in the next segment.
