Excerpts from Supreme Master Ching Hai’s Lecture:
The Light inside, the Light of the extreme intelligence, is without shadow and substance; that's why we can hardly see it with our eyes. Even if sometimes we see it with the Wisdom, which doesn't need eyes, we still feel like it hurts our eyes even, our physical eyes. But then afterwards we will be used to it, and then it feels like when we look into a very ordinary daylight time and it doesn't hurt anymore.
Some of the people asked me yesterday how is it like when you are going into Samadhi state? You know like ... He asked me whether the highest level is that you become nothing, you are not aware of your body, not aware of the environment and all that. This is not even the highest state.
In the highest, state you are able to function in the daily life just as an ordinary being while having a super awareness surpassing that of the mind-computer, of all things that are going on in the universe.
