Without going out of my door

I can know all things of earth

Without looking out of my window

I could know the ways of heaven

The farther one travels

The less one knows

The less one really knows

Without going out of your door

You can know all things of earth

Without looking out of your window

You could know the ways of heaven

The farther one travels

The less one knows

The less one really knows

Arrive without travelling

See all without looking

Do all without doing
