Only a person who has seen ultimate reality directly, on the Path of Seeing, truly understands the two realities. The experience is called “indescribable,” only because the seer cannot convey it to another person in words that can make that person see it, on the spot. But of course a seer devotes the rest of his life to helping others see ultimate reality too.
And this is because the simple act of seeing, if only for a number of minutes, destroys certain negative emotions immediately— and all others not long afterward, bringing the freedom that all of us so desperately need.
In the hours after you first see, you pass through a series of extraordinary visions. One of these is seeing directly into the future, to the day when you will become a being of light who helps all other living creatures. And so all doubts about your future, for example, vanish forever.
These two are very personal experiences that can never be fully conveyed to those who have not seen. However much the seer may want to share them, however much he may say or write, he cannot remove every last doubt of those who have yet to shatter the Great Mistake.
