When you wake up and find tea by your bedside, drink the tea.

 
People who are unwell may find that their options appear to be limited. Waking with a dry mouth and eyes and a hammering heart, they wonder if they are going to be able to get up this morning; then they find (this time) that they can do it. They get up and go do a few chores, then find themselves short of breath and the hammer heart has not gone away, which is a little new. They go back to bed and sleep at midday, then awaken to find there is a cup of tea left for them on the side table by a concerned family member. It's not quite hot; that was an unexpectedly long nap.

Perhaps they struggle up again, re-heat the tea, and, spilling a little (Oh, hot!), wander out back to sit in the sun, going over what chores remain that could be done somehow. "I might move that little ash tree that came up in the lawn, find it a safer home. I wonder where the shovel for that is."

Planning a task is not failure to be in the moment. Those who go out shopping must sequence their activities: "bag, check. List, check. Keys, check. Phone, check. Okay, bring a cup of tea for the old-timer and say I'm going out. Oh, she's out cold. Well, she'll figure it out. I'll just tiptoe away."

All these activities are miracles of right now. Planning and listing are the sort of thing those new to zen may feel they must struggle against, but not so. The past vanishes into memory and the future is merely ideation, but these memories and ideas are indubitably part of the present moment.

The trick is to be all of you all the time, because you are all of the universe, with its air and warmth and tea passing through "you," along with the sound of jays out back for the old-timer and the changing colors of the traffic light for the shopper. If what you are doing is what you are doing, inhabit all of it, like a star shining into all parts of its stellar system and on into the great beyond.

Katagiri says: 

Taking care of right now is coping with an emergency case. So when a moment comes, whatever happens, just face your life as it really is, giving away any ideas of good or bad, and try your best to carry out what you have to do. You can do this; you can face your life with a calm mind and burn the flame of your life in whatever you do. This is Buddha’s practice. That’s why teachers always tell you to practice, devote yourself to doing something, and forget yourself. When you forget yourself and put your wholehearted effort into facing every moment, you can do something, and simultaneously you can rest in the continuous flow of life energy. Then you really enjoy your life. 

Suzuki adds:

Knowing that your life is short, to enjoy it day after day, moment after moment, is the life of "form is form, and emptiness emptiness." When Buddha comes, you will welcome him; when the devil comes, you will welcome him. The famous Chinese Zen master Ummon, said, "Sun-faced Buddha and moon-faced Buddha." When he was ill, someone asked him, "How are you?" And he answered, "Sun-faced Buddha and moon-faced Buddha." That is the life of "form is form and emptiness is emptiness." There is no problem. One year of life is good.
