When you fight in 'high heavenly stance' which is a term i've coined for arts like boxing where the legs are appromaxitly straight (Ni, Si). Being introverted is being tall, N/S are legs, used for running. Like a buffalo escapes from a lion. But high heavenly can't run as a big cat because it doesnt have endurance. However, when the legs are straight, the arms are lifted up making it stronger muscle-wise and then the arms provides 'control'. A big cat has control. But a buffalo, not tall a dwarf can kill a lion if it goes head on because it has a powerful strike that could possibly break through control defense. https://www.karateforums.com/targeting-vs-controlling-vt51028.html P is striking hard with fast legs and low defense. J is great control/defense but lower striking power.
