Just being a watcher, a witness is insight. Witness is highest growth of consciousness. If there is no witnessing and we indulge in events we are in dark night of soul. Waking mode of mind looks so real and tangible to us and we never doubt events in waking mode and the entity which sees the events. Doubt is part of dark night, but it is a search for rising Sun, but once you have reached the rising Sun, dark night goes and with it doubt too. Self- inquiry is doubting the seer, the "me," the ego, the self. Once you know doubt, ego commits suicide on its own accord. Doubt that is written in scripture, otherwise you will be confusion. Truth has to be experienced, not believed. So all belief systems are illusions. Organized religions are organized belief systems and so they are illusions. If you seek for reward you will miss the fact. You are a collection of problems and it is a fact. Enlightenment is way of extinction of of problems which have their origin in Self- ignorance. Practicing everything without sense of attainment is profound transcendent wisdom which cuts of source of cycle of birth and death like a sword. The source is identity with sensations which occur to us. Enlightenment is third eye that looks inwards with awareness which can be recognized only by those who have looked a little inwards. Trying to attain Self creates anxiety and tension. We pay attention to wrong things in objective reality. We don't pay attention to movement of own self and its mechanics of functioning which is right attention. Thoughts belong to nature, so known and they are material in nature and so they are limited. We are using thought to solve every human problem through thought which is intrinsically limited and so divisive. Naturally thought cannot solve all human problems. Thought has a lace in solving physical problems. Being a response of memory it cannot solve a living problem in psyche but we are using thought for this purpose also making the things much more complicated and the present condition of society is the proof for it. Society is based on sense of separation, ambition, greed, violence, fear, desire, pleasure, fragmentary outlook of life. So we have to take leap from thought which is known to unknowable and for that leap, meditation is the jumping board and meditation is state of mind in which there is no-thought. There is cessation thought activity in meditation. Meditation is non- discriminative awareness without judgment, evaluation but mind is discriminative awareness with judgment and evaluation because primarily it is meant for physical and dead things. So at psychological level we require witnessing consciousness and at physical level we require discriminative awareness in form of thought. Mind knows only one language-that is of fear, danger, how to survive and make yourself safe against an antagonistic universe.
