When I had my insight after coming across the Three Principles, I experienced what I can only explain as a period of little or no personal thought for 3 days.
And during that time I experienced a number of profound insights. But when I try to explain the insights, the words are never adequate.
I can say things like "everyone is beautiful", or "we are all connected and
all equal", or "there is a level of unconditional and impersonal love that is completely different from any personal feeling of love that we have ever experienced before" or that "unconditional impersonal love is fundamentally what we are all made up of",
or "we are living a complete illusion" or "everything is perfect" or "we will all be perfectly OK no matter what happens, even if we die".. but these are all just words, and they often fall flat.
