What is spiritual transcendence? Can you give an example? Or have you ever experienced it?
In religion, transcendence is a condition or state of being that surpasses physical existence, and in one form is also independent of it. It is affirmed in the concept of the divine in the major religious traditions, and contrasts with the notion of God, or the Absolute existing exclusively in the physical order (immanentism), or indistinguishable from it (pantheism). Transcendence can be attributed to the divine not only in its being, but also in its knowabilty. Thus, God transcends the universe, but also transcends knowledge (is beyond the grasp of the human mind). Although transcendence is defined as the opposite of immanence, the two are not necessarily mutually exclusive. Some theologians and metaphysicians of the great religious traditions affirm that God, or Brahman, is both within and beyond the universe (panentheism); in it, but not of it; simultaneously pervading it and surpassing it.
Personally, God transcended into my life/heart when I accepted Jesus Christ as my Lord and Savior when I was 9 years old.
You should look into Sri Aurobindo, the Mother, and their community in India, Auroville. I have experienced something similar to transcendence but not quite the same. That was like tasting a drop of rain compared to drinking heavily from the stream.
