It's an interesting question. I use this ID because I have experienced it while meditating and I consider it as one of my greatest experience. During that state,all in the Universe is united in one,
oneness (恬淡虚无)
no " body", no mind, no myself. Only from that moment when myself doesn't exit, can I really understand who I am, what "unconditional love' and "慈悲" mean.

The experience is also a milestone for meditation practice. I know I am on the right path, nothing can stop me to find the truth. With more practice and the third eye opening, more and more knowledge and understanding comes naturally. Only after that in recent years I started to read the Bible, Buddhist sutras and some spirit books to verify my knowledge and understanding from meditation is correct.
In my opinion,The Law of one series are some of the greatest books we have ever had. The thing is, in spirit field no matter how great a book is , how many times you read about it, you can never get enlightened by reading it, you just know it, you can never really understand what it talk about without higher dimension experience.

Thanks
