“To study the nature of this experience is rather a difficult matter. All that one can hope to do is to set down a few general impressions. It is a type of experience which is not clearly differentiated into a subject-object state, an integral, undivided consciousness in which not merely this or that side of man’s nature but his whole being seems to find itself. It is a condition of consciousness in which feelings are fused, ideas melt into one another, boundaries broken and ordinary distinctions transcended. Past and present fade away in a sense of timeless being. Consciousness and being are not there different from each other. All being is consciousness and all consciousness being. Thought and reality coalesce and a creative merging of subject and object results. Life grows conscious of its incredible depths. In this fulness of felt life and freedom, the distinction of the knower and the known disappears. The privacy of the individual self is broken into an invaded by a universal self which the individual feels as his own.
The experience itself is felt to be sufficient and complete. It does not come in a fragmentary or truncated form demanding completion by something else. It does not look beyond itself for meaning or validity. It does not appeal to external standards of logic or metaphysics. It is its own cause and explanation. It is sovereign in its own rights and carries its own credentials. It is self-established (svatahsiddha), self-evidencing (svasamvedya), self-luminous (svayamprakasa). It does not argue or explain but it knows and is.”
