Greater Sheng prevails, looking at the long-term result.
Just as in many times of crisis, a mother chooses to sacrifice herself to preserve her child, and a soldier chooses to sacrifice himself to defend his country, it looks at the future result: the mother feels the child is more long-lasting than herself, and the soldier feels the country is more prosperous than himself, thus they make the choice of Long Sheng.
Take the deep and far for the two Sheng, take the trivial for the two Mie.
Greater Sheng prevails, is the decision-making principle when facing a dilemma.
"Greater" refers to the expectation of the result, not the scale at the time.
If both lead to Sheng, see which one is more magnificent in the future; if both lead to Mie, see which one is more infinitesimal in the future.
