strings: Only when the mind is completely silent not only on the upper level but fundamentally, right through, on both the superficial and the deeper levels of consciousness—only then can the unknown come into being. The unknown is not something to be experienced by the mind; silence alone can be experienced, nothing but silence. If the mind experiences anything but silence, it is merely projecting its own desires and such a mind is not silent; so long as the mind is not silent, so long as thought in any form, conscious or unconscious, is in movement, there can be no silence. Silence is freedom from the past, from knowledge, from both conscious and unconscious memory; when the mind is completely silent, not in use, when there is the silence which is not a product of effort, then only does the timeless, the eternal come into being. That state is not a state of remembering— there is no entity that remembers, that experiences.
