The descent of a celestial phenomenon is a recognition from the heavens.

To trigger such a phenomenon oneself is to touch the heavens.

Though they seem similar, there is a vast difference. Those above the Impeccable Golden Body Stage can easily trigger phenomena, but it's exceedingly difficult for the heavens to actively bestow one.

When the heavens bestow a phenomenon, it is an acknowledgment of extraordinary achievements, a profound affirmation from the universe.
