what you have observed is very true. Bhagavan has quoted at several instances about how the world is not without 'i' only when the seer exists, the seen also exists. His classic question for contemplation is really wonderful, where was all the world during sushupti (deep sleep) ? It is really very thought provoking revelation every time. But, we never are scared of sleeping, ie. getting lost to sleep, everyday, we do not feel scarfed to sleep at all, and, even when we are awake, we have an inherent desire to sleep further, moreover, even though, it is not our direct perception, we still are able to say, i slept well.
The scriptures have at various instances referred to the deep sleep as the closest aid to grasp the nirvikalpa sahaj samadhi, the saints wonderfully expressed as Jagrath Sushupti, Thungamal Thunguvadu (Waking sleep)
Even though we may sleep without getting scared of losing ourselves to oblivion, somewhere, unconsciously, one 'knows' that one can never lose oneself to oblivion, hence, with this light, one enjoys deep sleep.
Bhagavan once said to Muruganar, when some discussion was going on about death, where some were talking about how every people in the world, even though they see so many deaths, still, they are not shaken by the limitedness of this body and the world, what an ignorance it is, to which Bhagavan expressed that this does not occur due to ignorance, but only due to pure knowledge, that each one does not get shaken even after seeing so many deaths. Somewhere, from within, a light of knowledge reveals its own immortality.
So, it goes to reveal to ourselves, how this knowledge is present as glaring effulgence and continuously, like thousand suns, still, it is only due to sheer forgetfulness that this is being missed out.
In is interesting to note here, the expressions of Jnaneshwar, who says, that the Self forgets itself completely only to relish the joy of realising/knowing Thyself again. But can this forgetfulness really be called a forgetfulness? It is like a mother playing Hide and Seek with her small child by closing her face by her palms.
Therefore, truly speaking, even ignorance, as well, occurs only out of the light of Self itself, like, if the clouds hide the sun, does it mean that the Sun has disappeared? The joy of Sun is only enhanced when there is darkness, and the joy of darkness is only enhanced when there is sun. one does not exist without the other. It is in the presence of THAT, that, even these leelas of dualities is able to occur, which itself is beyond these dualities. Duality exists to realise Advaita, and Advaita exists to realise Duality.Similarly, Jnaneshwar goes on to express, that ignorance exists only when knowledge exists, and knowledge too, exists only in relation to ignorance.
In such a pure knowledge, Jnaneshwar expresses in ecstatic outpouring that, The same Self became 2 in order to realise its Oneness, the same self(nose) became a flower in order to smell the fragrance. The Guru became Shishya in order to reveal the Self, and the same Self Became a mirror in order to see itself.
What a Joy, is this Leela of Self. Gratitude.
