This sutra (a Buddhist word which may be translated as “teaching”) is a discourse on the nature of Nirvana, or enlightenment. Avalokitesvara explains that personality, the very nature of human consciousness, is impermanent and dream-like; whereas the state of liberation, referred to here as Nirvana or the highest Samadhi, is the ultimate reality beyond all knowledge and identification. Therefore, the ego-self never can never attain or achieve enlightenment. Rather, the elements of the personality---the sensations, thoughts and mental constructs that make up our sense of self---must be dissolved, and the sense of self relinquished altogether. Only then can we transcend the confines of our human identity and awaken to the timeless, universal realm of Prajna-paramitra, the perfect wisdom. The seeker is instructed to investigate the nature of the self, and realize it's ultimate emptiness firsthand through the practice of meditation and contemplation.
