The death

I would like to ask why the “Death in Motion” which was thought by Samaels successor, Rabolu, why is it not thought in the lectures by the instructors? By reading his work it is clear that it is very effective in eliminating the defects that constitute the ego, which in turn starves the ego and makes it shrink over time. It is made clear by Rabolu that when people were meditating on egos they weren’t getting anywhere and remained asleep. With the death in motion you die truly from moment to moment, instant to instant.

Would the “death in motion” in combination with learning to mediate and comprehend the ego be super effective rather than just relying on one aspect of the death?

I would like to hear your thoughts, and if the instructors did teach the death in motion, could you link the lectures please.

thanks.
