You are THAT!

“The opposite of a mundane truth is untrue, but the opposite of a deep truth is also true.”

There is no Death in the Absolute sense, but in the waking state, death happens all the time; actually, all there is conditioned, perishable has a time stamp. Everything is finite in the waking state.

Many seek attainment in the form of samadhi, but it is futile as you will attain it anyway when you leave your mortal body. Attaining by meditation/tantra are some ways, as is Surrendering. In that timeless state, you encounter Perfect Brilliant Stillness, presumably like after death. Having this experience is very rare and unusual; many people delude themselves or often lie about having attainment as if it was some badge of honor or accomplishment. Welcome to “guru business.”

All religions claim you go to a particular place, yet you never really leave the Self. Your separation is only an illusion, and your life is an illusion. You are already Enlightened; you don’t know it yet. That is precisely why some call this process self-realization. You have already arrived; there is nothing to do but experience it. Mere acceptance and mindfulness, as the New Age like to call is inadequate and misleading. Resulting in life-altering rebirth; experiencing is the goal and necessity. The Direct Experience also eliminates any doubts and inner conflicts that permeate faith.

We never die as we were never born in the first place. What is inevitable is that you will not go anywhere; you are already there. You leave your body as if it was an old suit, that is all.
“The real you is timeless and beyond life and death. The body will survive as long as it is needed. It doesn’t have to live long.” (Nisargadatta Maharaj)
“No one ever experiences their death. No one ever will. By definition, it is not possible. The most widely accepted definition of physical death is ‘brain death,’ flatline; no sensory perceptions, and no processing of perceptions; no thought, emotion, memory, or internal activity of any kind; therefore, we call it no experience. Death is the ceasing of experience in that body/mind. Therefore, if there is no experience in that body/mind, there can be no experience of death in that body/mind.
It’s similar to falling asleep. In all the times you have fallen asleep, you have never experienced it. You experience being drowsy; you experience lying down, getting sleepier – next thing you know, you are waking up and postulating that, at some point, you must have fallen asleep. Still, you do not have a direct experience of that because the one who would have experienced falling asleep, had it been awake, had fallen asleep!”

Your separation is only an illusion, and your life is an illusion. We never die as we never truly live. What is inevitable is that you will not go anywhere; you are already there. You leave your body as if it was an old suit, that is all.
