Q: Enlightened masters can leave the body at their will so why would they need a disease to leave the body?
A; Sometimes they can leave their body at will. One more thing, when they leave the body at their will also, some time they will dump the body and it falls into some disease. Sometimes straight away they leave and go. It is the way of dropping. You just drop the cup or sometimes they just leave the cup on the table. Sometimes they feel bored and they don't even feel like putting the cup on the table. They just leave their hands and the cup drops and breaks as in the case of Ramakrishna and Ramana Maharishi.
Some people keep their cup on the table like Paramahamsa Yogananda. His body was so beautifully pure; nothing damaged, no disturbance; he straight away left and went away. He just put the cup on the table. He took that much of time and energy. He just took that much and said ahhh I drop it, I dump it.
How to do it is each one's will. It is up to them, their will. Some masters leave their body at will, some just drop. It is their will. But it is no way related to their enlightenment.
Q: In the gap of meditation yesterday I could see my awareness very clearly as a singularity and I was able to hold it and it dissolved quietly. If this awareness is my true nature then who was observing it?
A: When you are in that awareness itself nobody is observing. Only after coming out there is observer and awareness. If the observer also is not there, only then are you in awareness. If you have the observer and awareness then you are not in awareness. You are playing the game in the mind, I am aware, I am aware. You are repeating the thought, I am aware. You are not aware. Repeating the thought I am aware is not awareness. So if you are not having even that thought only then you are aware.
Q: We are unclutched to begin with. Can we help by using tatvam asi or remembrance, or is that also not needed?
A: Again you are connecting me with Sankara. Again you are connecting me with Vyasa. Do not even remember new words like tatvamasi and all those things. Just remember that, you are unclutched, and be with that.
