Chano-yu ceremony was used as the way of leading many retainers,subordinates, by the Lord in Sengoku period. (I mistook the word "lord" in last time post.I'm sorry.)
The Lord Nobunaga was the collector of many precious tea utensils.
When his retainers did the good job,(for example,win the war) he gave his precious tea utensils to the retainers as rewards.
Such rewards as precious tea utensils were used for boosting the motivation of retainers.They were used for increasing the mood of subordinates.
Gradually,tea ceremony became the status symbol for samurai.They show off their status power by opening the tea ceremony.(Tea ceremony was permitted only distinguished retainers in Nobunaga era.)
Tea ceremony was also the only place where samurai had relaxing,pleasant time,after they had appalling wars.
