How to interpret Rumi's Poem Inn

Inn A person's life is like an inn.

There are new visitors every morning.

Happiness, depression, meanness, a moment of consciousness,

Like an unexpected guest.

Welcome and warmly entertain each and every one of them!

Even a group of sad people,

Destroy your house,

Empty all the furniture,

Be polite.

Because he may bring some new happiness.

Purify your mind.

Whether it's gloomy thoughts, shame or evil thoughts,

Everyone should smile at the door,

Welcome them into your heart.

Whoever comes should be grateful,

Because every visitor

It's all a guide from heaven.
