This is Kawaguchi Hidetoshi. This is my humble answer to the question.
“What is samurai called in Buddhism? Please tell me more. Is there a definition for that? conditions or something?” ・・
Samadhi in Buddhism is a phonetic transcription with the etymology samadhi, and the point is what is called mental concentration in meditation, mental unity, etc. It is generally defined as having nine stages of meditation (four zen, four colorless, and exhaustive).
“Also, do you have training to lead to that? If you have an ascetic practice, what kind of thing do you do?” ・・
Typical examples are zazen meditation and meditation. Furthermore, there is an ascetic practice of concentrating on one act with one mind, which is also called a trifecta.
Now, the above is also described in the Wikipedia explanation of “Sanmai,” but in my humble opinion, I think that samurai is a state of understanding (emptiness).
This means understanding and understanding of emptiness in instinctive recognition, and direct knowledge; however, in the case of an ordinary man who is still immature in ascetic practice, even if the ascetic practice progresses to some extent, and even if he is able to enter a state of anamnesia, when he moves away from that ambivalence and returns to a world of manifestation, they are also misled by ignorance and worry, and they may create evil acts that cause reincarnation, confusion, and suffering.
Therefore, in the end, even if we return to the revealed world, it is necessary to aim for a state where emptiness is understood in its present quantity, and for that reason, I know that the practice of trifecta is also an important phased practice.
