 Your body should sleep, your mind should sleep, everything should sleep but you must be awake. Every day you have free enlightenment when you go to sleep but the problem is you're unconscious. You master your mortalities if you just manage to stay awake when you slip into sleep. There are various aspects to that which we refer to as Shiva. The boundless realities refer to as Shiva. The greatest of the yogis has been referred to as Shiva. His dance is referred to as Shiva, his music is referred to as Shiva. His stillness is referred to as Shiva. But of all this, he being a yogi is of the greatest importance in terms of opening up a door of possibility for every other human being. Somebody may be many things but for the world that dimension which is a possibility for the world is the most important thing. So he being a yogi is the most important thing. Being a yogi means many things. One aspect of a yogi is that he sleeps in his wakefulness and he's awake in his sleep. That this makes me fully awake but if you check the parameters of the body, it must be asleep. In sleep, everything should be asleep but you must be awake. The body should sleep, your mind should sleep, everything should sleep but you must be awake. When you fast asleep, you're in perfect tune with the existence, one with the existence, isn't it? Nature has given you this, if you've forgotten every day when you go to sleep, it makes you one with the existence. In the same sense of unity, if you can wake up and walk around, you made it, isn't it? Every day you have free enlightenment when you go to sleep but the problem is you're unconscious. So the sadhana essentially is just this that from wakefulness when you go to sleep, a certain part of you goes to sleep, a certain part of you if it still stays awake, then you made it. Otherwise when you wake up, a certain part of you still continues to sleep, then you made it. If you're awake and fast asleep at the same time, you're asleep and awake at the same time, this is called thurya. If you're in a state of thurya, we say you're a nruthunjaya, that means you're deathless because if you can be awake in your sleep, you will also be awake when you have to shed the body. So there is no question of death for such a person. Because life and death are happening at the same time. It is only the ignorant who think right now I'm alive and one day I will die. No, both are happening at the same time. They are not two different things actually, only for the sake of understanding, we have to divide them. Otherwise it's just life and life. One dimension of life and another dimension of life. So this transition between from one dimension of life to another becomes an easy doorway. Every day you have this doorway available to you, that is between wakefulness and sleep is as good as life and death. If you know how to exploit this doorway, if you stay alert till that last moment, do you ever know when you actually slept off? You think you're there but after some time you don't know when you slept. If you can take yourself to that moment, it's as good as being conscious at the moment of death. You master your mortality if you just manage to stay awake when you sleep into sleep. See, this is an opportunity for you. The best preparation for death is make an attempt to try to fall asleep consciously. Instead of drifting away if you shift from wakefulness to sleep consciously, death will become a plague. So the moment of sleep is a tremendous opportunity. If you sleep in a certain way, tomorrow morning when you wake up, you can be significantly one notch up. Every day you have this opportunity to practice death. If you can manage that moment, like you can do this consciously, right? Just like that, from wakefulness to sleep. If you can do it that way, that's it. You are both enjoying because there's no death for you.
