There is no perception or thought in Ein Sof whatsoever, since this matter is above our mind (The Study of the Ten Sefirot, Part 1, Chapter 1).
We cannot attain the Creator with our earthly mind. Therefore, the entire wisdom of Kabbalah is based on the methodology according to which a person changes his mind, his qualities, and his nature from reception to bestowal. To the extent that one acquires the quality of bestowal, one can feel the Creator in it.
