ICHIGO-ICHIE:the philosophy of the Zen and Tea

write;
When a person asked Sen-no-Rikyu the secret of the tea ceremony,
Rikyu answered like this.
"You should not take care about your entertaining a guest so in many cases.
A visitor needs to feel it cool in summer.
A visitor needs to feel it warm in winter.
Carry out the fire of a sunken hearth to such an extent that hot water boils.
Offer tea at the temperature which is easy to drink.
This is the secret of the tea ceremony. "
These things are that even only 3-year-old small child can understand.
However, even an 80-year-old old man is difficult for carrying these all out to perfection.
In a usual life, we entertain people using the heart of Zen,It is best to render you yourself consideration.
