तुर्य

Turya (or चतुर्थ ) is a state of pure consciousness, or the experience of ultimate reality and truth. It is a fourth state of consciousness that underlies and transcends the three common states of consciousness: the state of waking consciousness (जगराता), the state of dreaming (स्वप्न) , and dreamless sleep (सुसुप्ति)

"The fourth state is not that which is conscious of the subjective, nor that which is conscious of the objective, nor that which is conscious of both, nor that which is simple consciousness, nor that which is all-sentient mass, nor that which is all darkness. It is unseen, transcendent, the sole essence of the consciousness of self, the completion of the world"
