Full poem:

Vimalakirti is not sick when he is sick, but he has forgotten his luck at home.

Why does Emperor Wei need a pill and seven bowls of tea with him?

Vernacular translation: The eminent monk Vimalakirti fell ill. Elder Vimalakirti knew that Manjusri and the Buddhist disciples were coming, so he used his magical power to empty the room, leaving him with nothing but sleeping on a bed. When Manjushri Bodhisattva entered the room, he asked the elder Vimalakirti about his illness. Xie Lingyun is already a secular person traveling around. Wherever Emperor Wei's elixir of life is needed, all he needs is the seven cups of strong tea in Tang Lu's poem.

Source: From Su Shi's seven-character quatrain of the Northern Song Dynasty, "Wandering to the Buddha's Houses, Drinking Hot Tea in One Day, Playing with Shu Qinshi's Wall with Seven Cups".
