Our world is defined by thought-forms, but we see the limits of intellect when we attempt to understand the Self, for the Self cannot possibly be confined within the limitations of one's mind.
Thoughts come and go and therefore cannot be taken as real. The only thing that is real is that which neither comes nor goes – that which is permanent and absolute. To see that thoughts come and go, is to let them come and go and not hold on to them, nor pursue them, nor deny them, but to know them for what they are – mere fleeting impressions on the surface of the Self that is you. To see thoughts for what they are is to move beyond thinking to the silence that is of the nature of the Self.
