Amazing the wording itself, here, particularly in writing.
In writing the word( Meng, 悶), of the unhappiness( due to the stuffy/bored/pensive): got the letter as lock between the right/left gate, status about getting closed. closed inside of the house, with the right/left doors stopped. We do equip with the ability to move ourself from the negative to the positive. Thus, we could get the interior well cleaned while spending the time at the outdoors. Let heart feel/experience the fresh/new more, get ourselves more tolerant. Thus, heart itself becomes the shining sun, brighten up us mentally, and get the surrounding even shining.
In writing the word( Mein, 門), of the traditional Chinese gates, got the right and left wooden boards. Gate to the house, similar as, the situation of per the mental and the physical to a person, and both legs/feet to a body. Keep them in good condition, as possible as we could. Get rest for a while( even few days), when it’s needed. Enjoyably Yours, Love365**
