Like on a foggy day we cannot perceive the firmament, inside the dense bubble of thought we cannot perceive our true nature. 
Living the me-assumption, we are deluded in believing and feeling mortality, birth and death haunt us. 
Under the spell of personhood, the shining light of awareness eludes us and we remain isolated in the bubble of thought and sensory impressions. 
Our outlook remains external, dualistic, veiling the vastness of being/awareness. 
Sooner or later we are bound to take a closer look. A fresh looking, wondering, investigating that does not rely on the regurgitated past. 
We may realize the borderlessness of aware presence and recognize ourselves as that. 
Recognition that all is that. Ending the mistaken identification, ending the unhappiness in the dream. 
Namaste.
