Lex ended up spending several days in meditation after watching the changes take place within his system. At first, he was merely interested since he found the change to be novel. But then his consciousness got drawn in, and Lex completely lost track of time and place. His mind drifted as he closed his eyes and ended up sitting cross legged on the floor, absorbing everything he had seen.
This was both a good thing and a bad thing for Lex.
It was a good thing because he encountered a natural state of epiphany, falling into a meditative trance and qualitatively enhancing his understanding and application of laws as a whole.
It was a bad thing because the moment he woke up from meditation, his growth was much too substantial to push back the tribulation anymore.
