Therefore, masters of tea ceremony customarily feed the used chasen to the flames to show their gratitude, and this service is called chasen kuyo in the same manner as hari kuyo (memorial service for dull and broken needles) and fude kuyo (memorial service for used brushes).
そこで使い終えた茶筅を焚き上げて感謝の意を示すのが茶人の習いとなっており、針供養、筆供養などと同様に茶筅供養と呼ばれている。
