A common western rebuke to countries that had communist revolutions were that the revolutionary leader stayed in power for decades until their death. Joseph Stalin. Mao Zedong. Fidel Castro's power passed to his brother five years before he died, so he does not fit the cookie cutter mode fully.

Another rebuke is how the communist party filled a religious or even feudal void to some extent - Lenin's tomb in Red Square being a perfect example. I can assure you that though the Politburo felt that was a needed measure, they did feel a bit silly and embarrassed about having to do it.

Why was all of this felt necessary within the Politburo? The answer is simple, in fact the answer is somewhat answered in this essay, if parallels are allowed for. Before the revolution, all revolutionaries were true believers who faced prison, exile and death fighting against impossible odds for years and decades. Those who join the party after the success of the revolution are always feared to be the parallel of the middle manager MBA managing up. A Gorbachev, a Yeltsin. The cadre around Deng Xiaoping who reversed his purge from the party and then put him in power.

A very different circumstance, but in many ways analogous.
