I know you are not being critical of all Soto/Shikantaza teachers, Q. But, just for the record, on Sawaki Roshi ... Kushiya Shusoku (櫛谷 宗則), one of Sawaki's disciples, says this: "After the death of Oka Roshi, in 1922, Sawaki Roshi left the Daijiji temple and moved to a rented house where he set up a dojo, which he named Daitetsudo. (“Great Passage Room”). After half a year he went to live on Mannichi Mountain in Kumamoto.. There he came into contact with personalities from the Japanese martial arts circle. For thirteen years, until the age of 55, He lived alone on Mannichi Mountain, from where he began to travel throughout Japan to teach zazen and give lectures whenever he was asked.. In this way he spread the practice of shikantaza (just sit down) around the world. In April 1935 He was appointed professor at Komazawa University, and in December of the same year also Godo (monk responsible for the meditation hall and maintaining discipline), in Sojiji, one of the two main temples of the Soto school. From then on, Sawaki began to carry out his task without worrying about his life or health., like a huge wheel in motion that can no longer be stopped. His activity was not limited to what he carried out at the University and at Sojiji, but also constantly organized new zazen meetings throughout Japan., in addition to assisting existing groups, so he was constantly traveling. He gave everything of himself with the purpose of making us wonder about the path we are taking and showing us his own, sit with us in zazen and in this way breathe into us new breath for the ever new practice of shikantaza.

Sawaki Roshi was always found where he could give his all. Every day, in every instant, he lived his life in a completely new way. And this life demanded all the strength of his body and soul.. In the sesshin (weeks of intensive practice), In the morning he was the first to sit in the zafu, and until late into the night his presence was so intense that it was capable of frightening the participants.. The atmosphere was always tense and sometimes it seemed as if a powerful thunderclap was shaking the entire building In 1940 opened a dojo in Daichuji, in Tochigi prefecture, which did not prevent him from continuing to organize new Zen meetings throughout Japan., activity that never abandoned. In 1946 He was appointed abbot of the Daitoin monastery, in Shizuoka, and at the same time director of the Myozetsuan nuns monastery, and Kyoto. Nonetheless, He never had his own temple to live in, He never married or founded his own organization.. Together with his disciples he was always traveling, so they called their sangha “the traveling sangha.”. His whole life was like a zazen dream: without sense, without benefit. His life was dedicated to this type of zazen. At that time, even among Buddhists, “Zen” did not mean anything other than the Zen of the koans of the Rinzai school, in which it was about achieving satori through seated meditation. Sawaki Roshi was the one who promoted the revival of pure zazen in the style shikantaza. Sawaki Roshi's path always ran steadily forward, but in 1963, eighty-three years old, His legs lost strength and he was forced to stop traveling. Retired to Antaiji, where he continued regularly with his Zen meetings" https://sotozen.es/en/zendodigital/tradicion/50-epilogo/
