The sorcerers' struggle for assuredness is the most dramatic struggle there is. It's painful and costly. Many, many times it has actually cost sorcerers their lives.
In order for any sorcerer to have complete certainty about his actions, or about his position in the sorcerers' world, or to be capable of utilizing intelligently his new continuity, he must invalidate the continuity of his old life. Only then can his actions have the necessary assuredness to fortify and balance the tenuousness and instability of his new continuity.

The sorcerer seers of modern times call this process of invalidation the ticket to impeccability, or the sorcerers' symbolic but final death.
