Maika-sama
This is Kawaguchi Hidetoshi. This is my humble answer to the question.
As his final teaching, Shakyamuni said, “All events pass away (impermanent). Complete your training without neglecting.” That's what you said.
“Be indomitable (when).”
These are his last words, and they are thought to be one of the most important words of Shakyamuni.
Shakyamuni explained Buddhism with “good, clever, and convenient” for enlightenment and nirvana.
It's an “countermeasure theory” and “medicine for illness.”
Of course, Mahayana Buddhism is also included within it.
However, I believe that Mahayana and other classifications are meaningless even if they are thought of too separately.
Anyway, please think that all of Shakyamuni's teachings are governed in principle by the four sacred truths, the “Four Holy Sages.”
“... Among the teachings in Buddhism, the crux of that is above all else is the “Four Holy Traces” in the “First Dharma Wheel” that Buddha first taught, and that is, for example, we are in the midst of eight pains, but those suffering always have a causal relationship (cause and condition) that leads to the result of that suffering, and we have suffered, and somehow resolve the causal relationship that brought about that suffering to better results If it is possible to turn it into a causal relationship to drive away, suffering can eventually be destroyed, and furthermore, by practicing Buddhism, the Buddha explained the methodology for doing so by making full use of counterfactual theory, goodness, and convenience, assuming that it is something that will eventually lead to enlightenment and nirvana. ・・”
I would like to firmly move towards enlightenment and nirvana by learning and practicing these teachings in a “shape that fits (the shape that fits also changes in various ways depending on causation (cause and condition)” that suits each one without neglecting.
Bodhisattvas are practitioners of wisdom and good fortune (merit), and among them, there is an impression that they place emphasis on practicing good fortune, but everyone should work on practicing wisdom and good fortune (merit) in order to attain enlightenment and nirvana. As a “form” of ascetic practitioners, I don't think it's necessary to think about it too separately.
I want to continue working on Buddhism “unrelenting.” Let's work hard together.
