Every fear you accumulate, every fear makes you feel agitated, every fear which you do not want to think or remember – go through, go into all those fears consciously neither deciding to save yourself from that fear nor having greed to achieve what you are afraid of. So without having the greed or fear enter into the fear. Naturally the fear will lose its quality of fear when you do not carry fear or greed for the fear. Greed has its quality of greed because you are greed for greed and fear about the greed. Same way the fear has the quality of fear because you are fear for the fear and indirect greed towards the fear. So when your fears are approached with fearlessness and greedlessness, the straightening out of your consciousness every day happens.
The change of consciousness from Jagrath to Swapna, Swapna to Sushupthi ; The waking state to dream state and dream state to the deep sleep state happens because your awareness is not straightened out. Either the bumps of the fear or bumps of the greed responsible for your consciousness jumping from waking state to dream state or dream state to deep sleep state. If you remove all the bumps of the fear before falling asleep you will not fall asleep, you will fall into something called restful awareness, which is recorded by the word – Turiya – by the earlier mantra drashtas. So the word Turiya denotes the state of falling into the restful awareness without the bumps of fear or greed. Every night remove all the bumps you created during your day time through fear or greed. Continous practice of removing all the bumps of fear and greed by facing them will help you to fall into the state of Turiya. This is what Mahadeva calls as Death process – Nirbhaya Dhyana.
